195-421: Music theory is the study of theoretical frameworks for understanding the practices and possibilities of music . The Oxford Companion to Music describes three interrelated uses of the term "music theory": The first is the " rudiments ", that are needed to understand music notation ( key signatures , time signatures , and rhythmic notation ); the second is learning scholars' views on music from antiquity to

585-421: A chord progression (a sequence of chords), which is the norm in small jazz and blues groups. Rehearsals of orchestras, concert bands and choirs are led by a conductor. Rock, blues and jazz bands are usually led by the bandleader. A rehearsal is a structured repetition of a song or piece by the performers until it can be sung or played correctly and, if it is a song or piece for more than one musician, until
780-408: A computer screen . In ancient times, music notation was put onto stone or clay tablets. To perform music from notation, a singer or instrumentalist requires an understanding of the rhythmic and pitch elements embodied in the symbols and the performance practice that is associated with a piece of music or genre. In genres requiring musical improvisation , the performer often plays from music where only
975-637: A "self-portrait, a gesture of friendship, prescription for an ideal party... [and] an environment consisting solely of what is most ardently loved". Amateur musicians can compose or perform music for their own pleasure and derive income elsewhere. Professional musicians are employed by institutions and organisations, including armed forces (in marching bands , concert bands and popular music groups), religious institutions, symphony orchestras, broadcasting or film production companies, and music schools . Professional musicians sometimes work as freelancers or session musicians , seeking contracts and engagements in
1170-672: A Latin translation from the Hebrew Old Testament and the Greek New Testament . Gutenberg's invention made mass production of texts possible for the first time. Although the Gutenberg Bible itself was expensive, printed books began to spread widely over European trade routes during the next 50 years, and by the 16th century, printed books had become more widely accessible and less costly. While many textbooks were already in use, compulsory education and
1365-461: A defense to scare off predators. Prehistoric music can only be theorized based on findings from paleolithic archaeology sites. The disputed Divje Babe flute , a perforated cave bear femur , is at least 40,000 years old, though there is considerable debate surrounding whether it is truly a musical instrument or an object formed by animals. The earliest objects whose designations as musical instruments are widely accepted are bone flutes from
1560-586: A degree program and tuition and fees are lower, the average estimated cost of books and supplies per first-time, full-time student was $ 886 in academic year 2003–2004, representing almost three-quarters of the cost of tuition and fees. According to the 2nd edition of a study by the United States Public Interest Research Group (US PIRG) published in February 2005 : "Textbook prices are increasing at more than four times
1755-602: A distance from actual musical practice. But this medieval discipline became the basis for tuning systems in later centuries and is generally included in modern scholarship on the history of music theory. Music theory as a practical discipline encompasses the methods and concepts that composers and other musicians use in creating and performing music. The development, preservation, and transmission of music theory in this sense may be found in oral and written music-making traditions, musical instruments , and other artifacts . For example, ancient instruments from prehistoric sites around
1950-455: A faculty order for the book at the end of the term and the edition is still current, they may offer students the wholesale price of the book, which could range from 5 to 35 percent of the new retail price, according to the GAO report. When students resell their textbooks during campus "buyback" periods, these textbooks are often sold into the national used textbook distribution chain. If a textbook

Africa is too diverse to make firm generalizations, but the musicologist J. H. Kwabena Nketia has emphasized African music's often inseparable connection to dance and speech in general. Some African cultures, such as

Darwin's original perspective has been heavily criticized for its inconsistencies with other sexual selection methods, though many scholars in the 21st century have developed and promoted the theory. Other theories include that music arose to assist in organizing labor, improving long-distance communication, benefiting communication with the divine , assisting in community cohesion or as
2535-499: A given meter. Syncopated rhythms contradict those conventions by accenting unexpected parts of the beat. Playing simultaneous rhythms in more than one time signature is called polyrhythm . In recent years, rhythm and meter have become an important area of research among music scholars. The most highly cited of these recent scholars are Maury Yeston , Fred Lerdahl and Ray Jackendoff , Jonathan Kramer , and Justin London. A melody
2730-648: A greater or lesser degree. Context and many other aspects can affect apparent dissonance and consonance. For example, in a Debussy prelude, a major second may sound stable and consonant, while the same interval may sound dissonant in a Bach fugue. In the Common practice era , the perfect fourth is considered dissonant when not supported by a lower third or fifth. Since the early 20th century, Arnold Schoenberg 's concept of "emancipated" dissonance, in which traditionally dissonant intervals can be treated as "higher," more remote consonances, has become more widely accepted. Rhythm
2925-408: A kiosk and ordering books online with a third party facilitator or renting directly from the store's inventory. Some stores use a hybrid of both methods, opting for in-store selections of the most popular books and the online option for more obscure titles or books they consider too risky to put in the rental system. Rented items can be used for a set duration of time, then are required to be returned to
3120-467: A large scale by ordering textbooks for entire courses at lower prices from international distribution channels. While the 1998 Supreme Court decision Quality King v. L'anza protects the reimportation of copyrighted materials under the first-sale doctrine , textbook publishers have still attempted to prevent the U.S. sale of international editions by enforcing contracts which forbid foreign wholesalers from selling to American distributors. Concerned about
3315-553: A lighter, clearer and considerably simpler texture than the Baroque music which preceded it. The main style was homophony , where a prominent melody and a subordinate chordal accompaniment part are clearly distinct. Classical instrumental melodies tended to be almost voicelike and singable. New genres were developed, and the fortepiano , the forerunner to the modern piano, replaced the Baroque era harpsichord and pipe organ as
3510-417: A loophole through this definition in state bills. Given that the problem of high textbook prices is linked to the "broken" economics of the market, requiring publishers to disclose textbook prices to faculty is a solution pursued by a number of legislatures. By inserting price into sales interactions, this regulation will supposedly make the economic forces operate more normally. No data suggests that this
3705-524: A loss of sales for U.S. retailers. Additionally, the availability of lower-priced textbooks through these channels has heightened distrust and frustration among students regarding textbook prices, and college stores find it difficult to explain why their textbook prices are higher, according to the National Association of College Stores. Retailers and publishers have also been concerned that some U.S. retailers may have engaged in reimportation on
3900-558: A new diversity in theatre music , including operetta , and musical comedy and other forms of musical theatre. In the 19th century, a key way new compositions became known to the public was by the sales of sheet music , which middle class amateur music lovers would perform at home, on their piano or other common instruments, such as the violin. With 20th-century music , the invention of new electric technologies such as radio broadcasting and mass market availability of gramophone records meant sound recordings heard by listeners (on
4095-474: A new edition costs 12% more than a new copy of the previous edition (not surprising if the old version is obsolete), and 58% more than a used copy of the previous edition. Textbook publishers maintain these new editions are driven by demand from teachers. That study found that 76% of teachers said new editions were justified "half of the time or less" and 40% said they were justified "rarely" or "never". The PIRG study has been criticized by publishers, who argue that

#17327800415924290-629: A number of textbooks already exist, and are being used at schools such as MIT and Harvard. A 2010 study published found that open textbooks offer a viable and attractive means to meet faculty and student needs while offering savings of approximately 80% compared to traditional textbook options. Although the largest question seems to be who is going to pay to write them, several state policies suggest that public investment in open textbooks might make sense. To offer another perspective , any jurisdiction might find itself challenged to find sufficient numbers of credible academics who would be willing to undertake
4485-668: A particular composition. During the Baroque period, emotional associations with specific keys, known as the doctrine of the affections , were an important topic in music theory, but the unique tonal colorings of keys that gave rise to that doctrine were largely erased with the adoption of equal temperament. However, many musicians continue to feel that certain keys are more appropriate to certain emotions than others. Indian classical music theory continues to strongly associate keys with emotional states, times of day, and other extra-musical concepts and notably, does not employ equal temperament. Consonance and dissonance are subjective qualities of
4680-514: A performer learns a song " by ear ". When the composer of a song or piece is no longer known, this music is often classified as "traditional" or as a "folk song". Different musical traditions have different attitudes towards how and where to make changes to the original source material, from quite strict, to those that demand improvisation or modification to the music. A culture's history and stories may also be passed on by ear through song. Music has many different fundamentals or elements. Depending on
4875-426: A performer. Although a musical composition often uses musical notation and has a single author, this is not always the case. A work of music can have multiple composers, which often occurs in popular music when a band collaborates to write a song, or in musical theatre, when one person writes the melodies, a second person writes the lyrics, and a third person orchestrates the songs. In some styles of music, such as
5070-487: A pipe, he found its sound agreeable and named it huangzhong , the "Yellow Bell." He then heard phoenixes singing. The male and female phoenix each sang six tones. Ling Lun cut his bamboo pipes to match the pitches of the phoenixes, producing twelve pitch pipes in two sets: six from the male phoenix and six from the female: these were called the lülü or later the shierlü . Apart from technical and structural aspects, ancient Chinese music theory also discusses topics such as
5265-399: A price quote or offer. These online book buyers often offer "free shipping" (which in actuality is built into the offer for the book), and allow students to sell multiple books to the same source. Because online book buyers are buying books for resale, the prices they offer may be lower than students can get on online marketplaces. However, their prices are competitive, and they tend to focus on
5460-438: A relationship between the origin of music and the origin of language , and there is disagreement surrounding whether music developed before, after, or simultaneously with language. A similar source of contention surrounds whether music was the intentional result of natural selection or was a byproduct spandrel of evolution. The earliest influential theory was proposed by Charles Darwin in 1871, who stated that music arose as
5655-628: A royalty, saving 80% or more when compared to traditional textbook options. An example print on demand open textbook title, "College Algebra" by Stitz & Zeager through Lulu is 608 pages, royalty free, and costs about $ 20 ordered one at a time (March 2011). (Any print on demand service could be used – this is just an example. School districts could easily negotiate even lower prices for bulk purchases to be printed in their own communities.) Teacher's editions are available for educators and parents. Titles have been authored by various individuals and organizations and are vetted for quality prior to inclusion in
5850-510: A science of sounds". One must deduce that music theory exists in all musical cultures of the world. Music theory is often concerned with abstract musical aspects such as tuning and tonal systems, scales , consonance and dissonance , and rhythmic relationships. There is also a body of theory concerning practical aspects, such as the creation or the performance of music, orchestration , ornamentation , improvisation, and electronic sound production. A person who researches or teaches music theory
6045-442: A small commission only after the sale is completed. According to textbook author Henry L. Roediger (and Wadsworth Publishing Company senior editor Vicki Knight), the used textbook market is illegitimate, and entirely to blame for the rising costs of textbooks. As methods of "dealing with this problem", he recommends making previous editions of textbooks obsolete, binding the textbook with other materials, and passing laws to prevent

6240-457: A song may state the song is a "slow blues" or a "fast swing", which indicates the tempo and the genre. To read notation, a person must have an understanding of music theory , harmony and the performance practice associated with a particular song or piece's genre. Written notation varies with the style and period of music. Nowadays, notated music is produced as sheet music or, for individuals with computer scorewriter programs, as an image on
6435-521: A source of ideas for classical music. Igor Stravinsky , Arnold Schoenberg , and John Cage were influential composers in 20th-century art music. The invention of sound recording and the ability to edit music gave rise to new subgenres of classical music, including the acousmatic and Musique concrète schools of electronic composition. Sound recording was a major influence on the development of popular music genres, because it enabled recordings of songs and bands to be widely distributed. The introduction of
6630-528: A strong, insistent back beat, and a catchy melody." The traditional rhythm section for popular music is rhythm guitar, electric bass guitar, drums. Some bands have keyboard instruments such as organ, piano, or, since the 1970s, analog synthesizers . In the 1980s, pop musicians began using digital synthesizers, such as the DX-7 synthesizer, electronic drum machines such as the TR-808 and synth bass devices (such as
6825-427: A student receives. If a professor chooses to use the same book the following semester, even if it is a custom text, designed specifically for an individual instructor, bookstores often buy the book back. The GAO report found that, generally, if a book is in good condition and will be used on the campus again the next term, bookstores will pay students 50 percent of the original price paid. If the bookstore has not received
7020-779: A surging or "pushed" attack, or fortepiano ( fp ) for a loud attack with a sudden decrease to a soft level. The full span of these markings usually range from a nearly inaudible pianissississimo ( pppp ) to a loud-as-possible fortissississimo ( ffff ). Greater extremes of pppppp and fffff and nuances such as p+ or più piano are sometimes found. Other systems of indicating volume are also used in both notation and analysis: dB (decibels), numerical scales, colored or different sized notes, words in languages other than Italian, and symbols such as those for progressively increasing volume ( crescendo ) or decreasing volume ( diminuendo or decrescendo ), often called " hairpins " when indicated with diverging or converging lines as shown in
7215-468: A textbook. Supplemental items range from CD-ROMs and workbooks to online passcodes and bonus material. Students often cannot buy these things separately, and often the one-time-use supplements destroy the resale value of the textbook. According to the Student PIRGs, the typical bundled textbook costs 10%–50% more than an unbundled textbook, and 65% of professors said they "rarely" or "never" use
7410-468: A theoretical nature, mainly lists of intervals and tunings . The scholar Sam Mirelman reports that the earliest of these texts dates from before 1500 BCE, a millennium earlier than surviving evidence from any other culture of comparable musical thought. Further, "All the Mesopotamian texts [about music] are united by the use of a terminology for music that, according to the approximate dating of
7605-677: A tradition of other treatises, which are cited regularly just as scholarly writing cites earlier research. In modern academia, music theory is a subfield of musicology , the wider study of musical cultures and history. Guido Adler , however, in one of the texts that founded musicology in the late 19th century, wrote that "the science of music originated at the same time as the art of sounds"., where "the science of music" ( Musikwissenschaft ) obviously meant "music theory". Adler added that music only could exist when one began measuring pitches and comparing them to each other. He concluded that "all people for which one can speak of an art of sounds also have
7800-426: A variety of settings. There are often many links between amateur and professional musicians. Beginning amateur musicians take lessons with professional musicians. In community settings, advanced amateur musicians perform with professional musicians in a variety of ensembles such as community concert bands and community orchestras. A distinction is often made between music performed for a live audience and music that
7995-436: A vibrant tradition of secular song (non-religious songs). Examples of composers from this period are Léonin , Pérotin , Guillaume de Machaut , and Walther von der Vogelweide . Renaissance music ( c. 1400 to 1600) was more focused on secular themes, such as courtly love . Around 1450, the printing press was invented, which made printed sheet music much less expensive and easier to mass-produce (prior to

Some students save money by buying used copies of textbooks, which tend to be less expensive, and are available from many college bookstores in the US, who buy them back from students at the end of a term. Books that are not being re-used at the school are often purchased by an off-campus wholesaler for 0–30% of

The medieval music era (500 to 1400), which took place during the Middle Ages , started with the introduction of monophonic (single melodic line) chanting into Catholic Church services. Musical notation was used since ancient times in Greek culture , but in
8580-494: Is a balance between "tense" and "relaxed" moments. Timbre, sometimes called "color", or "tone color," is the principal phenomenon that allows us to distinguish one instrument from another when both play at the same pitch and volume, a quality of a voice or instrument often described in terms like bright, dull, shrill, etc. It is of considerable interest in music theory, especially because it is one component of music that has as yet, no standardized nomenclature. It has been called "...
8775-518: Is a core component and an essential criterion of performances. Music is composed and performed for many purposes, ranging from aesthetic pleasure, religious or ceremonial purposes, or as an entertainment product for the marketplace. When music was only available through sheet music scores, such as during the Classical and Romantic eras, music lovers would buy the sheet music of their favourite pieces and songs so that they could perform them at home on
8970-412: Is a genre of popular music that developed in the 1950s from rock and roll , rockabilly , blues , and country music . The sound of rock often revolves around the electric or acoustic guitar, and it uses a strong back beat laid down by a rhythm section . Along with the guitar or keyboards, saxophone and blues-style harmonica are used as soloing instruments. In its "purest form", it "has three chords,
9165-409: Is a group of musical sounds in agreeable succession or arrangement. Because melody is such a prominent aspect in so much music, its construction and other qualities are a primary interest of music theory. The basic elements of melody are pitch, duration, rhythm, and tempo. The tones of a melody are usually drawn from pitch systems such as scales or modes . Melody may consist, to increasing degree, of
9360-799: Is a music theorist. University study, typically to the MA or PhD level, is required to teach as a tenure-track music theorist in a US or Canadian university. Methods of analysis include mathematics, graphic analysis, and especially analysis enabled by western music notation. Comparative, descriptive, statistical, and other methods are also used. Music theory textbooks , especially in the United States of America, often include elements of musical acoustics , considerations of musical notation , and techniques of tonal composition ( harmony and counterpoint ), among other topics. Several surviving Sumerian and Akkadian clay tablets include musical information of
9555-453: Is an additional chord member that creates a relatively dissonant interval in relation to the bass. It is part of a chord, but is not one of the chord tones (1 3 5 7). Typically, in the classical common practice period a dissonant chord (chord with tension) "resolves" to a consonant chord. Harmonization usually sounds pleasant to the ear when there is a balance between the consonant and dissonant sounds. In simple words, that occurs when there
9750-402: Is broad enough to include the creation of popular music and traditional music songs and instrumental pieces as well as spontaneously improvised works like those of free jazz performers and African percussionists such as Ewe drummers . Performance is the physical expression of music, which occurs when a song is sung or piano piece, guitar melody, symphony, drum beat or other musical part
9945-428: Is called aleatoric music , and is associated with contemporary composers active in the 20th century, such as John Cage , Morton Feldman , and Witold Lutosławski . A commonly known example of chance-based music is the sound of wind chimes jingling in a breeze. The study of composition has traditionally been dominated by examination of methods and practice of Western classical music, but the definition of composition

#173278004159210140-402: Is called an interval . The most basic interval is the unison , which is simply two notes of the same pitch. The octave interval is two pitches that are either double or half the frequency of one another. The unique characteristics of octaves gave rise to the concept of pitch class : pitches of the same letter name that occur in different octaves may be grouped into a single "class" by ignoring
10335-464: Is common in folk music and blues . Non-Western cultures often use scales that do not correspond with an equally divided twelve-tone division of the octave. For example, classical Ottoman , Persian , Indian and Arabic musical systems often make use of multiples of quarter tones (half the size of a semitone, as the name indicates), for instance in 'neutral' seconds (three quarter tones) or 'neutral' thirds (seven quarter tones)—they do not normally use

Music is often characterized as a highly versatile medium for expressing human creativity . Diverse activities are involved in the creation of music, and are often divided into categories of composition , improvisation , and performance . Music may be performed using a wide variety of musical instruments , including

Music is composed of aural phenomena; "music theory" considers how those phenomena apply in music. Music theory considers melody, rhythm, counterpoint, harmony, form, tonal systems, scales, tuning, intervals, consonance, dissonance, durational proportions, the acoustics of pitch systems, composition, performance, orchestration, ornamentation, improvisation, electronic sound production, etc. Pitch

Chinese classical music , the traditional art or court music of China, has a history stretching over about 3,000 years. It has its own unique systems of musical notation, as well as musical tuning and pitch, musical instruments and styles or genres. Chinese music

Their most recent study found that 77% of faculty say publisher sales representatives do not volunteer prices, and only 40% got an answer when they directly asked. Furthermore, the study found that 23% of faculty rated publisher websites as "informative and easy to use" and less than half said they typically listed

Textbook A textbook is a book containing a comprehensive compilation of content in a branch of study with the intention of explaining it. Textbooks are produced to meet the needs of educators, usually at educational institutions. Schoolbooks are textbooks and other books used in schools. Today, many textbooks are published in both print and digital formats. The history of textbooks dates back to ancient civilizations. For example, Ancient Greeks wrote educational texts. The modern textbook has its roots in

However, there are also many cases where a live performance in front of an audience is also recorded and distributed. Live concert recordings are popular in both classical music and in popular music forms such as rock, where illegally taped live concerts are prized by music lovers. In

However, as it gets performed, the interpretation of a song or piece can evolve and change. In classical music, instrumental performers, singers or conductors may gradually make changes to the phrasing or tempo of a piece. In popular and traditional music,

The time signature or meter signature specifies how many beats are in a measure, and which value of written note is counted or felt as a single beat. Through increased stress, or variations in duration or articulation, particular tones may be accented. There are conventions in most musical traditions for regular and hierarchical accentuation of beats to reinforce
13065-553: Is the lowness or highness of a tone , for example the difference between middle C and a higher C. The frequency of the sound waves producing a pitch can be measured precisely, but the perception of pitch is more complex because single notes from natural sources are usually a complex mix of many frequencies. Accordingly, theorists often describe pitch as a subjective sensation rather than an objective measurement of sound. Specific frequencies are often assigned letter names. Today most orchestras assign concert A (the A above middle C on
13260-414: Is used in a number of different contexts. The two most common contexts can be differentiated by describing them as the "rudimentary elements of music" and the "perceptual elements of music". Pitch is an aspect of a sound that we can hear, reflecting whether one musical sound, note, or tone is "higher" or "lower" than another musical sound, note, or tone. We can talk about the highness or lowness of pitch in

The Latin word itself derives from the Ancient Greek mousiké ( technē )— μουσική ( τέχνη )—literally meaning "(art) of the Muses". The Muses were nine deities in Ancient Greek mythology who presided over the arts and sciences . They were included in tales by the earliest Western authors, Homer and Hesiod , and eventually came to be associated with music specifically. Over time, Polyhymnia would reside over music more prominently than

Examples range from avant-garde music that uses graphic notation , to text compositions such as Aus den sieben Tagen , to computer programs that select sounds for musical pieces. Music that makes heavy use of randomness and chance
14820-460: The chord changes and form of the song are written, requiring the performer to have a great understanding of the music's structure, harmony and the styles of a particular genre e.g., jazz or country music . In Western art music, the most common types of written notation are scores, which include all the music parts of an ensemble piece, and parts, which are the music notation for the individual performers or singers. In popular music, jazz, and blues,
15015-427: The fugue , the invention , the sonata , and the concerto . The late Baroque style was polyphonically complex and richly ornamented. Important composers from the Baroque era include Johann Sebastian Bach ( Cello suites ), George Frideric Handel ( Messiah ), Georg Philipp Telemann and Antonio Vivaldi ( The Four Seasons ). The music of the Classical period (1730 to 1820) aimed to imitate what were seen as
15210-541: The human voice . It can also be composed, sequenced, or otherwise produced to be indirectly played mechanically or electronically, such as via a music box , barrel organ , or digital audio workstation software on a computer. Music often plays a key role in social events and religious ceremony . The techniques of making music are often transmitted as part of a cultural tradition. Music is played in public and private contexts, highlighted at events such as festivals and concerts for various different types of ensembles. Music
15405-413: The jam band scene, live, improvised jam sessions are preferred to studio recordings. Music notation typically means the written expression of music notes and rhythms on paper using symbols. When music is written down, the pitches and rhythm of the music, such as the notes of a melody , are notated. Music notation often provides instructions on how to perform the music. For example, the sheet music for
15600-423: The multitrack recording system had a major influence on rock music , because it could do more than record a band's performance. Using a multitrack system, a band and their music producer could overdub many layers of instrument tracks and vocals, creating new sounds that would not be possible in a live performance. Jazz evolved and became an important genre of music over the course of the 20th century, and during
15795-476: The recording and reproduction of music has historically included sheet music , microphones , phonographs , and tape machines , with playback of digital musics being a common use for MP3 players , CD players , and smartphones . The modern English word ' music ' came into use in the 1630s. It is derived from a long line of successive precursors: the Old English ' musike ' of the mid-13th century;
15990-462: The sasando stringed instrument on the island of Rote, the Sundanese angklung , and the complex and sophisticated Javanese and Balinese gamelan orchestras. Indonesia is the home of gong chime , a general term for a set of small, high pitched pot gongs. Gongs are usually placed in order of note, with the boss up on a string held in a low wooden frame. The most popular form of Indonesian music
16185-592: The syncretism of exploring different art-forms in a musical context, (such as literature), history (historical figures and legends), or nature itself. Romantic love or longing was a prevalent theme in many works composed during this period. In some cases, the formal structures from the classical period continued to be used (e.g., the sonata form used in string quartets and symphonies ), but these forms were expanded and altered. In many cases, new approaches were explored for existing genres, forms, and functions. Also, new forms were created that were deemed better suited to
16380-543: The 2007 edition of the College Board's Trend in College Pricing Report published October 2007 : "College costs continue to rise and federal student aid has shown slower growth when adjusted for inflation, while textbooks, as a percentage of total college costs, have remained steady at about 5 percent." In most U.S. K-12 public schools, a local school board votes on which textbooks to purchase from
16575-455: The 20th and early 21st century, as "common practice" Western art music performance became institutionalized in symphony orchestras, opera houses, and ballets, improvisation has played a smaller role, as more and more music was notated in scores and parts for musicians to play. At the same time, some 20th and 21st century art music composers have increasingly included improvisation in their creative work. In Indian classical music , improvisation
16770-457: The Amazon kindle, e-textbooks are not an innovation, but have been "gaining momentum". According to the article " Are textbooks obsolete?", publishers and editorials are concerned about the issue of expensive textbooks. "The expense of textbooks is a concern for students, and e-textbooks, address the face of the issue, Williams says " As publishers we understand the high cost of these materials, and
16965-558: The Americas have words for music that refer specifically to song but describe instrumental music regardless. Though the Arabic musiqi can refer to all music, it is usually used for instrumental and metric music, while khandan identifies vocal and improvised music. It is often debated to what extent the origins of music will ever be understood, and there are competing theories that aim to explain it. Many scholars highlight
17160-529: The CK-12 catalog. An effort is underway to map state educational standards correlations. Stanford University provided a number of titles in use. Curriki is another modular K-12 content non-profit "empowering educators to deliver and share curricula." Selected Curriki materials are also correlated to U.S. state educational standards. Some Curriki content has been collected into open textbooks and some may be used for modular lessons or special topics. Similar to
17355-412: The Classical period was the development of public concerts. The aristocracy still played a significant role in the sponsorship of concerts and compositions, but it was now possible for composers to survive without being permanent employees of queens or princes. The increasing popularity of classical music led to a growth in the number and types of orchestras. The expansion of orchestral concerts necessitated
17550-437: The Classical style of sonata is completely distinct. All of the main instrumental forms of the Classical era, from string quartets to symphonies and concertos, were based on the structure of the sonata. The instruments used chamber music and orchestra became more standardized. In place of the basso continuo group of the Baroque era, which consisted of harpsichord, organ or lute along with a number of bass instruments selected at
17745-696: The Flat World financial model sustainable. However, in January 2013 Flat World Knowledge announced their financial model could no longer sustain their free-to-read options for students. Flat World Knowledge intends to have open textbooks available for the 125 highest-enrolled courses on college campuses within the next few years. CK-12 Flexbooks are the open textbooks designed for United States K-12 courses. CK-12 FlexBooks are designed to facilitate conformance to national and United States and individual state textbook standards. CK-12 FlexBooks are licensed under
17940-626: The ISBN or title, author and edition, most textbooks can be located through online used booksellers or retailers. Most leading textbook companies publish a new edition every 3 or 4 years, more frequently in math and science. Harvard economics chair James K. Stock has stated that new editions are often not about significant improvements to the content. "New editions are to a considerable extent simply another tool used by publishers and textbook authors to maintain their revenue stream, that is, to keep up prices." A study conducted by The Student PIRGs found that
18135-680: The Middle Ages, notation was first introduced by the Catholic Church, so chant melodies could be written down, to facilitate the use of the same melodies for religious music across the Catholic empire. The only European Medieval repertory that has been found, in written form, from before 800 is the monophonic liturgical plainsong chant of the Catholic Church, the central tradition of which was called Gregorian chant . Alongside these traditions of sacred and church music there existed
18330-478: The Western art music tradition, improvisation was an important skill during the Baroque era and during the Classical era. In the Baroque era, performers improvised ornaments, and basso continuo keyboard players improvised chord voicings based on figured bass notation. As well, the top soloists were expected to be able to improvise pieces such as preludes . In the Classical era, solo performers and singers improvised virtuoso cadenzas during concerts. However, in
18525-653: The Western tradition. During the thirteenth century, a new rhythm system called mensural notation grew out of an earlier, more limited method of notating rhythms in terms of fixed repetitive patterns, the so-called rhythmic modes, which were developed in France around 1200. An early form of mensural notation was first described and codified in the treatise Ars cantus mensurabilis ("The art of measured chant") by Franco of Cologne (c. 1280). Mensural notation used different note shapes to specify different durations, allowing scribes to capture rhythms which varied instead of repeating
18720-444: The actual price the publisher would get for the book. Once a textbook is purchased from a retailer for the first time, there are several ways a student can sell his/her textbooks back at the end of the semester or later. Students can sell to 1) the college/university bookstore; 2) fellow students; 3) numerous online websites; or 4) a student swap service. As for buyback on a specific campus, faculty decisions largely determine how much
18915-482: The aim of reselling them for a profit. Like online marketplaces, online book buyers operate year-round, giving students the opportunity to sell their books even when campus "buyback" periods are not in effect. Online book buyers, who are often online book sellers as well, will sometimes disclaim whether or not a book can be sold back prior to purchase. Students enter the ISBN numbers of the books they wish to sell and receive
19110-487: The building of large public performance spaces. Symphonic music including symphonies, musical accompaniment to ballet and mixed vocal/instrumental genres, such as opera and oratorio , became more popular. The best known composers of Classicism are Carl Philipp Emanuel Bach , Christoph Willibald Gluck , Johann Christian Bach , Joseph Haydn , Wolfgang Amadeus Mozart , Ludwig van Beethoven and Franz Schubert . Beethoven and Schubert are also considered to be composers in
19305-541: The bundled items in their courses. A 2005 Government Accountability Office (GAO) Report in the United States found that the production of these supplemental items was the primary cause of rapidly increasing prices: While publishers, retailers, and wholesalers all play a role in textbook pricing, the primary factor contributing to increases in the price of textbooks has been the increased investment publishers have made in new products to enhance instruction and learning...While wholesalers, retailers, and others do not question
19500-465: The charges for returned books from bookstores. According to the National Association of College Stores, the entire cost of the book is justified by expenses, with typically 11.7% of the price of a new book going to the author's royalties (or a committee of editors at the publishing house), 22.7% going to the store, and 64.6% going to the publisher. The store and publisher amounts are slightly higher for Canada. Bookstores and used-book vendors profit from
19695-470: The chord C major may be described as a triad of major quality built on the note C . Chords may also be classified by inversion , the order in which the notes are stacked. A series of chords is called a chord progression . Although any chord may in principle be followed by any other chord, certain patterns of chords have been accepted as establishing key in common-practice harmony . To describe this, chords are numbered, using Roman numerals (upward from
19890-616: The church to aristocratic courts, kings, queens and princes competed for the finest composers. Many leading composers came from the Netherlands, Belgium, and France; they are called the Franco-Flemish composers. They held important positions throughout Europe, especially in Italy. Other countries with vibrant musical activity included Germany, England, and Spain. The Baroque era of music took place from 1600 to 1750, coinciding with
20085-462: The composer typically orchestrates his or her own compositions, but in musical theatre and in pop music, songwriters may hire an arranger to do the orchestration. In some cases, a songwriter may not use notation at all, and instead, compose the song in her mind and then play or record it from memory. In jazz and popular music, notable recordings by influential performers are given the weight that written scores play in classical music. Even when music
20280-443: The convenience of their service. Some even claim that buying used textbooks online and selling them to online book buyers has a lower total cost than even textbook rental services. In response to escalating textbook prices, limited competition, and to provide a more efficient system to connect buyers and sellers together, online textbook exchanges were developed. Most of today's sites handle buyer and seller payments, and usually deduct
20475-476: The copies of the textbook. Legislation at state and federal levels seeks to limit the practice of bundling, by requiring publishers to offer all components separately. Publishers have testified in favor of bills including this provision, but only in the case that the provision exempts the loosely defined category of "integrated textbooks". The Federal bill only exempts 3rd party materials in integrated textbooks, however publisher lobbyists have attempted to create
20670-442: The cost of textbooks and supplies for degree-seeking students as a percentage of tuition and fees varies by the type of institution attended. For example, the average estimated cost of books and supplies per first-time, full-time student for academic year 2003–2004 was $ 898 at 4-year public institutions, or about 26 percent of the cost of tuition and fees. At 2-year public institutions, where low-income students are more likely to pursue
20865-477: The country, or even different parts of the world, even if they could not afford to travel to these locations. This helped to spread musical styles. The focus of art music in the 20th century was characterized by exploration of new rhythms, styles, and sounds. The horrors of World War I influenced many of the arts, including music, and composers began exploring darker, harsher sounds. Traditional music styles such as jazz and folk music were used by composers as
21060-406: The creation of music notation , such as a sheet music "score", which is then performed by the composer or by other singers or musicians. In popular music and traditional music, the act of composing, which is typically called songwriting, may involve the creation of a basic outline of the song, called the lead sheet , which sets out the melody , lyrics and chord progression . In classical music,
21255-457: The definition of "element" being used, these can include pitch, beat or pulse, tempo, rhythm, melody, harmony, texture, style, allocation of voices, timbre or color, dynamics, expression, articulation, form, and structure. The elements of music feature prominently in the music curriculums of Australia, the UK, and the US. All three curriculums identify pitch, dynamics, timbre, and texture as elements, but
21450-401: The difference in octave. For example, a high C and a low C are members of the same pitch class—the class that contains all C's. Musical tuning systems, or temperaments, determine the precise size of intervals. Tuning systems vary widely within and between world cultures. In Western culture , there have long been several competing tuning systems, all with different qualities. Internationally,
21645-432: The discretion of the group leader (e.g., viol, cello, theorbo, serpent), Classical chamber groups used specified, standardized instruments (e.g., a string quartet would be performed by two violins, a viola and a cello). The practice of improvised chord-playing by the continuo keyboardist or lute player, a hallmark of Baroque music, underwent a gradual decline between 1750 and 1800. One of the most important changes made in
21840-443: The double-reed aulos and a plucked string instrument , the lyre , principally a special kind called a kithara . Music was an important part of education, and boys were taught music starting at age six. Greek musical literacy created significant musical development. Greek music theory included the Greek musical modes , that eventually became the basis for Western religious and classical music. Later, influences from
22035-481: The effects of differential pricing on college stores, the National Association of College Stores has called on publishers to stop the practice of selling textbooks at lower prices outside the United States. For example, some U.S. booksellers arrange for drop-shipments in foreign countries which are then re-shipped to America where the books can be sold online at used prices (for a "new" unopened book). The authors often getting half-royalties instead of full-royalties, minus
22230-415: The effort of creating an open textbook without realistic compensation, to make such a proposal work. Currently, some open textbooks have been funded with non-profit investment. The other challenge involves the reality of publishing, which is that textbooks with good sales and profitability subsidize the creation and publication of low demand but believed to be necessary textbooks. Subsidies skew markets and
22425-408: The electronic format permit us diminish the general expense of our content to the market". E-textbook applications facilitate similar experiences to physical textbooks by allowing the user to highlight and take notes in-page. These applications also extend textbook learning by providing quick definitions, reading the text aloud, and search functionality. In-store rentals are processed by either using
22620-548: The elimination of subsidies is disruptive; in the case of low demand textbooks the possibilities following subsidy removal include any or all of the following: higher retail prices, a switch to open textbooks, a reduction of the number of titles published. On the other hand, independent open textbook authoring and publishing models are developing. Most notably, the startup publisher Flat World Knowledge already has dozens of college-level open textbooks that are used by more than 900 institutions in 44 countries. Their business model
22815-457: The ever-expanding conception of what constitutes music , a more inclusive definition could be the consideration of any sonic phenomena, including silence. This is not an absolute guideline, however; for example, the study of "music" in the Quadrivium liberal arts university curriculum, that was common in medieval Europe , was an abstract system of proportions that was carefully studied at
23010-399: The field of books came with the 15th-century invention of printing with changeable type. The invention is attributed to German metalsmith Johannes Gutenberg, who cast type in molds using a melted metal alloy and constructed a wooden-screw printing press to transfer the image onto paper. Gutenberg's first and only large-scale printing effort was the now iconic Gutenberg Bible in the 1450s –
23205-650: The figure, motive, semi-phrase, antecedent and consequent phrase, and period or sentence. The period may be considered the complete melody, however some examples combine two periods, or use other combinations of constituents to create larger form melodies. A chord, in music, is any harmonic set of three or more notes that is heard as if sounding simultaneously . These need not actually be played together: arpeggios and broken chords may, for many practical and theoretical purposes, constitute chords. Chords and sequences of chords are frequently used in modern Western, West African, and Oceanian music, whereas they are absent from
23400-518: The first type (technical manuals) include More philosophical treatises of the second type include The pipa instrument carried with it a theory of musical modes that subsequently led to the Sui and Tang theory of 84 musical modes. Medieval Arabic music theorists include: The Latin treatise De institutione musica by the Roman philosopher Boethius (written c. 500, translated as Fundamentals of Music )
23595-698: The flourishing of the Baroque artistic style in Europe. The start of the Baroque era was marked by the penning of the first operas . Polyphonic contrapuntal music (music with separate, simultaneous melodic lines ) remained important during this period. German Baroque composers wrote for small ensembles including strings , brass , and woodwinds , as well as for choirs and keyboard instruments such as pipe organ , harpsichord , and clavichord . Musical complexity increased during this time. Several major musical forms were created, some of them which persisted into later periods, seeing further development. These include
23790-406: The graphic above. Articulation is the way the performer sounds notes. For example, staccato is the shortening of duration compared to the written note value, legato performs the notes in a smoothly joined sequence with no separation. Articulation is often described rather than quantified, therefore there is room to interpret how to execute precisely each articulation. For example, staccato
23985-999: The greatest music had no sounds. [...] Even the music of the qin zither , a genre closely affiliated with Confucian scholar-officials, includes many works with Daoist references, such as Tianfeng huanpei ("Heavenly Breeze and Sounds of Jade Pendants"). The Samaveda and Yajurveda (c. 1200 – 1000 BCE) are among the earliest testimonies of Indian music, but properly speaking, they contain no theory. The Natya Shastra , written between 200 BCE to 200 CE, discusses intervals ( Śrutis ), scales ( Grāmas ), consonances and dissonances, classes of melodic structure ( Mūrchanās , modes?), melodic types ( Jātis ), instruments, etc. Early preserved Greek writings on music theory include two types of works: Several names of theorists are known before these works, including Pythagoras ( c. 570 ~ c. 495 BCE ), Philolaus ( c. 470 ~ ( c. 385 BCE ), Archytas (428–347 BCE ), and others. Works of
24180-452: The inflation rate for all finished goods, according to the Bureau of Labor Statistics Producer Price Index. The wholesale prices charged by textbook publishers have jumped 62 percent since 1994, while prices charged for all finished goods increased only 14 percent. Similarly, the prices charged by publishers for general books increased just 19 percent during the same time period." According to
24375-432: The instrument and musical period (e.g. viol, wind; classical, baroque; etc.). Music Music is the arrangement of sound to create some combination of form , harmony , melody , rhythm , or otherwise expressive content . Music is generally agreed to be a cultural universal that is present in all human societies. Definitions of music vary widely in substance and approach. While scholars agree that music
24570-425: The interval between adjacent tones is called a semitone , or half step. Selecting tones from this set of 12 and arranging them in patterns of semitones and whole tones creates other scales. The most commonly encountered scales are the seven-toned major , the harmonic minor , the melodic minor , and the natural minor . Other examples of scales are the octatonic scale and the pentatonic or five-tone scale, which
24765-513: The interweaving of melodic lines, and polyphony , which refers to the relationship of separate independent voices, is thus sometimes distinguished from harmony. In popular and jazz harmony , chords are named by their root plus various terms and characters indicating their qualities. For example, a lead sheet may indicate chords such as C major, D minor, and G dominant seventh. In many types of music, notably Baroque, Romantic, modern, and jazz, chords are often augmented with "tensions". A tension
24960-519: The invention of the Greek alphabet 2,500 years ago, knowledge and stories were recited aloud, much like Homer 's epic poems. The new technology of writing meant stories no longer needed to be memorized, a development Socrates feared would weaken the Greeks' mental capacities for memorizing and retelling. (Ironically, we know about Socrates' concerns only because they were written down by his student Plato in his famous Dialogues.) The next revolution in
25155-650: The invention of the press, all notated music was hand-copied). The increased availability of sheet music spread musical styles quicker and across a larger area. Musicians and singers often worked for the church, courts and towns. Church choirs grew in size, and the church remained an important patron of music. By the middle of the 15th century, composers wrote richly polyphonic sacred music, in which different melody lines were interwoven simultaneously. Prominent composers from this era include Guillaume Du Fay , Giovanni Pierluigi da Palestrina , Thomas Morley , Orlando di Lasso and Josquin des Prez . As musical activity shifted from
25350-443: The issue of reimportation of pharmaceuticals into the U.S. market, the GAO report also highlights a similar phenomenon in textbook distribution. Retailers and publishers have expressed concern about the re-importation of lower-priced textbooks from international locations. Specifically, they cited the ability students have to purchase books from online distribution channels outside the United States at lower prices, which may result in
25545-471: The key elements of the art and philosophy of Ancient Greece and Rome: the ideals of balance, proportion and disciplined expression. (Note: the music from the Classical period should not be confused with Classical music in general, a term which refers to Western art music from the 5th century to the 2000s, which includes the Classical period as one of a number of periods). Music from the Classical period has
25740-425: The key-note), per their diatonic function . Common ways of notating or representing chords in western music other than conventional staff notation include Roman numerals , figured bass (much used in the Baroque era ), chord letters (sometimes used in modern musicology ), and various systems of chord charts typically found in the lead sheets used in popular music to lay out the sequence of chords so that
25935-508: The late Romantic period, composers explored dramatic chromatic alterations of tonality , such as extended chords and altered chords , which created new sound "colors." The late 19th century saw a dramatic expansion in the size of the orchestra, and the Industrial Revolution helped to create better instruments, creating a more powerful sound. Public concerts became an important part of well-to-do urban society. It also saw
26130-455: The later part of the Classical era, as it began to move towards Romanticism. Romantic music ( c. 1820 to 1900) from the 19th century had many elements in common with the Romantic styles in literature and painting of the era. Romanticism was an artistic, literary, and intellectual movement was characterized by its emphasis on emotion and individualism as well as glorification of all
26325-489: The location of the notes to be played on the instrument using a diagram of the guitar or bass fingerboard. Tablature was used in the Baroque era to notate music for the lute , a stringed, fretted instrument. Many types of music, such as traditional blues and folk music were not written down in sheet music ; instead, they were originally preserved in the memory of performers, and the songs were handed down orally , from one musician or singer to another, or aurally, in which
26520-480: The main keyboard instrument (though pipe organ continued to be used in sacred music, such as Masses). Importance was given to instrumental music. It was dominated by further development of musical forms initially defined in the Baroque period: the sonata , the concerto, and the symphony . Other main kinds were the trio , string quartet , serenade and divertimento . The sonata was the most important and developed form. Although Baroque composers also wrote sonatas,
26715-422: The mass production made possible by the printing press. Johannes Gutenberg himself may have printed editions of Ars Minor , a schoolbook on Latin grammar by Aelius Donatus . Early textbooks were used by tutors and teachers (e.g. alphabet books), as well as by individuals who taught themselves. The Greek philosopher Socrates lamented the loss of knowledge because the media of transmission were changing. Before
26910-427: The meter and mode of chanting. Indian classical music (marga) is monophonic , and based on a single melody line or raga rhythmically organized through talas . The poem Cilappatikaram provides information about how new scales can be formed by modal shifting of the tonic from an existing scale. Present day Hindi music was influenced by Persian traditional music and Afghan Mughals. Carnatic music , popular in
27105-440: The modern classical concert, religious processions, classical music festivals or music competitions . Chamber music , which is music for a small ensemble with only one or a few of each type of instrument, is often seen as more intimate than large symphonic works. Musical improvisation is the creation of spontaneous music, often within (or based on) a pre-existing harmonic framework, chord progression , or riffs . Improvisers use
27300-436: The moral character of particular modes. Several centuries later, treatises began to appear which dealt with the actual composition of pieces of music in the plainchant tradition. At the end of the ninth century, Hucbald worked towards more precise pitch notation for the neumes used to record plainchant. Guido d'Arezzo wrote a letter to Michael of Pomposa in 1028, entitled Epistola de ignoto cantu , in which he introduced
27495-416: The more general sense, such as the way a listener hears a piercingly high piccolo note or whistling tone as higher in pitch than a deep thump of a bass drum . We also talk about pitch in the precise sense associated with musical melodies , basslines and chords . Precise pitch can only be determined in sounds that have a frequency that is clear and stable enough to distinguish from noise. For example, it
27690-570: The music of many other parts of the world. The most frequently encountered chords are triads , so called because they consist of three distinct notes: further notes may be added to give seventh chords , extended chords , or added tone chords . The most common chords are the major and minor triads and then the augmented and diminished triads . The descriptions major , minor , augmented , and diminished are sometimes referred to collectively as chordal quality . Chords are also commonly classed by their root note—so, for instance,
27885-453: The musician may play accompaniment chords or improvise a solo. In music, harmony is the use of simultaneous pitches ( tones , notes ), or chords . The study of harmony involves chords and their construction and chord progressions and the principles of connection that govern them. Harmony is often said to refer to the "vertical" aspect of music, as distinguished from melodic line , or the "horizontal" aspect. Counterpoint , which refers to
28080-497: The nature and functions of music. The Yueji ("Record of music", c1st and 2nd centuries BCE), for example, manifests Confucian moral theories of understanding music in its social context. Studied and implemented by Confucian scholar-officials [...], these theories helped form a musical Confucianism that overshadowed but did not erase rival approaches. These include the assertion of Mozi (c. 468 – c. 376 BCE) that music wasted human and material resources, and Laozi 's claim that
28275-451: The new cost, for distribution to other bookstores. Some textbook companies have countered this by encouraging teachers to assign homework that must be done on the publisher's website. Students with a new textbook can use the pass code in the book to register on the site; otherwise they must pay the publisher to access the website and complete assigned homework. Students who look beyond the campus bookstore can typically find lower prices. With
28470-702: The new subject matter. Composers continued to develop opera and ballet music, exploring new styles and themes. In the years after 1800, the music developed by Ludwig van Beethoven and Franz Schubert introduced a more dramatic, expressive style. In Beethoven's case, short motifs , developed organically, came to replace melody as the most significant compositional unit (an example is the distinctive four note figure used in his Fifth Symphony ). Later Romantic composers such as Pyotr Ilyich Tchaikovsky , Antonín Dvořák , and Gustav Mahler used more unusual chords and more dissonance to create dramatic tension. They generated complex and often much longer musical works. During
28665-459: The notes of the chord, various scales that are associated with each chord, and chromatic ornaments and passing tones which may be neither chord tones nor from the typical scales associated with a chord. Musical improvisation can be done with or without preparation. Improvisation is a major part of some types of music, such as blues , jazz , and jazz fusion , in which instrumental performers improvise solos, melody lines, and accompaniment parts. In
28860-667: The number of providers has declined in recent years (there are just a handful of major textbook companies in the United States). Also, elasticity of demand is fairly low. The term "broken market" appeared in the economist James Koch's analysis of the market commissioned by the Advisory Committee on Student Financial Assistance. In the United States, the largest textbook publishers are Pearson Education , Cengage , McGraw-Hill Education , and Wiley . Together they control 90% of market revenue. Another textbook publisher
29055-742: The oldest, c. 43,150–39,370 BP. The earliest material and representational evidence of Egyptian musical instruments dates to the Predynastic period , but the evidence is more securely attested in the Old Kingdom when harps , flutes and double clarinets were played. Percussion instruments, lyres , and lutes were added to orchestras by the Middle Kingdom . Cymbals frequently accompanied music and dance, much as they still do in Egypt today. Egyptian folk music , including
29250-574: The other identified elements of music are far from universally agreed upon. Below is a list of the three official versions of the "elements of music": In relation to the UK curriculum, in 2013 the term: "appropriate musical notations " was added to their list of elements and the title of the list was changed from the "elements of music" to the "inter-related dimensions of music". The inter-related dimensions of music are listed as: pitch, duration, dynamics, tempo, timbre, texture, structure, and appropriate musical notations. The phrase "the elements of music"
29445-613: The other muses. The Latin word musica was also the originator for both the Spanish música and French musique via spelling and linguistic adjustment, though other European terms were probably loanwords , including the Italian musica , German Musik , Dutch muziek , Norwegian musikk , Polish muzyka and Russian muzïka . The modern Western world usually defines music as an all-encompassing term used to describe diverse genres, styles, and traditions. This
29640-581: The parts are together from a rhythmic and tuning perspective. Many cultures have strong traditions of solo performance (in which one singer or instrumentalist performs), such as in Indian classical music, and in the Western art-music tradition. Other cultures, such as in Bali , include strong traditions of group performance. All cultures include a mixture of both, and performance may range from improvised solo playing to highly planned and organized performances such as
29835-695: The past and nature. Romantic music expanded beyond the rigid styles and forms of the Classical era into more passionate, dramatic expressive pieces and songs. Romantic composers such as Wagner and Brahms attempted to increase emotional expression and power in their music to describe deeper truths or human feelings. With symphonic tone poems , composers tried to tell stories and evoke images or landscapes using instrumental music. Some composers promoted nationalistic pride with patriotic orchestral music inspired by folk music . The emotional and expressive qualities of music came to take precedence over tradition. Romantic composers grew in idiosyncrasy, and went further in
30030-444: The performance or perception of intensity, such as timbre, vibrato, and articulation. The conventional indications of dynamics are abbreviations for Italian words like forte ( f ) for loud and piano ( p ) for soft. These two basic notations are modified by indications including mezzo piano ( mp ) for moderately soft (literally "half soft") and mezzo forte ( mf ) for moderately loud, sforzando or sforzato ( sfz ) for
30225-428: The performers have more freedom to make changes to the form of a song or piece. As such, in popular and traditional music styles, even when a band plays a cover song , they can make changes such as adding a guitar solo or inserting an introduction. A performance can either be planned out and rehearsed (practiced)—which is the norm in classical music, jazz big bands , and many popular music styles–or improvised over
30420-454: The physical store or shipped back to the third party facilitator by the rental due date. Writing and highlighting is sometimes allowed in rented items, although excessive markup which makes the item unrentable is discouraged. Overdue items are often charged a fee up to the retail price of the rented item. Rented items typically do not include supplemental materials such as access codes, CDs, or loose-leafs. Using textbook sharing, students share
30615-428: The physical textbook with other students, and the cost of the book is divided among the users of the textbook. Over the life of the textbook, if 4 students use the textbook, the cost of the textbook for each student will be 25% of the total cost of the book. The latest trend in textbooks is "open textbooks". An open textbook is a free, openly licensed textbook offered online by the copyright holders. According to PIRG,
30810-584: The piano) to the frequency of 440 Hz. This assignment is somewhat arbitrary; for example, in 1859 France, the same A was tuned to 435 Hz. Such differences can have a noticeable effect on the timbre of instruments and other phenomena. Thus, in historically informed performance of older music, tuning is often set to match the tuning used in the period when it was written. Additionally, many cultures do not attempt to standardize pitch, often considering that it should be allowed to vary depending on genre, style, mood, etc. The difference in pitch between two notes
31005-469: The piano. With the advent of the phonograph , records of popular songs, rather than sheet music became the dominant way that music lovers would enjoy their favourite songs. With the advent of home tape recorders in the 1980s and digital music in the 1990s, music lovers could make tapes or playlists of favourite songs and take them with them on a portable cassette player or MP3 player. Some music lovers create mix tapes of favourite songs, which serve as
31200-401: The playing or singing style or phrasing of the melodies. Composers and songwriters who present their own music are interpreting their songs, just as much as those who perform the music of others. The standard body of choices and techniques present at a given time and a given place is referred to as performance practice , whereas interpretation is generally used to mean the individual choices of
31395-417: The practice of using syllables to describe notes and intervals. This was the source of the hexachordal solmization that was to be used until the end of the Middle Ages. Guido also wrote about emotional qualities of the modes, the phrase structure of plainchant, the temporal meaning of the neumes, etc.; his chapters on polyphony "come closer to describing and illustrating real music than any previous account" in
31590-495: The present; the third is a sub-topic of musicology that "seeks to define processes and general principles in music". The musicological approach to theory differs from music analysis "in that it takes as its starting-point not the individual work or performance but the fundamental materials from which it is built." Music theory is frequently concerned with describing how musicians and composers make music, including tuning systems and composition methods among other topics. Because of
31785-475: The price. The US Congress passed a law in the 2008 Higher Education Opportunity Act that would require price disclosure. Legislation requiring price disclosure has passed in Connecticut, Washington, Minnesota, Oregon, Arizona, Oklahoma, and Colorado. Publishers are currently supporting price disclosure mandates, though they insist that the "suggested retail price" should be disclosed, rather than
31980-402: The psychoacoustician's multidimensional waste-basket category for everything that cannot be labeled pitch or loudness," but can be accurately described and analyzed by Fourier analysis and other methods because it results from the combination of all sound frequencies , attack and release envelopes, and other qualities that a tone comprises. Timbre is principally determined by two things: (1)
32175-433: The quality of these materials, they have expressed concern that the publishers' practice of packaging supplements with a textbook to sell as one unit limits the opportunity students have to purchase less expensive used books....If publishers continue to increase these investments, particularly in technology, the cost to produce a textbook is likely to continue to increase in the future. Bundling has also been used to segment
32370-403: The quarter tone itself as a direct interval. In traditional Western notation, the scale used for a composition is usually indicated by a key signature at the beginning to designate the pitches that make up that scale. As the music progresses, the pitches used may change and introduce a different scale. Music can be transposed from one scale to another for various purposes, often to accommodate
32565-705: The radio or record player) became the main way to learn about new songs and pieces. There was a vast increase in music listening as the radio gained popularity and phonographs were used to replay and distribute music; anyone with a radio or record player could hear operas, symphonies and big bands in their own living room. During the 19th century, the focus on sheet music had restricted access to new music to middle and upper-class people who could read music and who owned pianos and other instruments. Radios and record players allowed lower-income people, who could not afford an opera or symphony concert ticket, to hear this music. As well, people could hear music from different parts of
32760-457: The range of a vocalist. Such transposition raises or lowers the overall pitch range, but preserves the intervallic relationships of the original scale. For example, transposition from the key of C major to D major raises all pitches of the scale of C major equally by a whole tone . Since the interval relationships remain unchanged, transposition may be unnoticed by a listener, however other qualities may change noticeably because transposition changes
32955-428: The recording digitally. In the 1990s, bands in genres such as nu metal began including DJs in their bands. DJs create music by manipulating recorded music, using a DJ mixer . "Composition" is the act or practice of creating a song, an instrumental music piece, a work with both singing and instruments, or another type of music. In many cultures, including Western classical music, the act of composing also includes
33150-407: The relationship of the overall pitch range compared to the range of the instruments or voices that perform the music. This often affects the music's overall sound, as well as having technical implications for the performers. The interrelationship of the keys most commonly used in Western tonal music is conveniently shown by the circle of fifths . Unique key signatures are also sometimes devised for
33345-518: The relative balance of overtones produced by a given instrument due its construction (e.g. shape, material), and (2) the envelope of the sound (including changes in the overtone structure over time). Timbre varies widely between different instruments, voices, and to lesser degree, between instruments of the same type due to variations in their construction, and significantly, the performer's technique. The timbre of most instruments can be changed by employing different techniques while playing. For example,
33540-442: The report contains factual inaccuracies regarding the annual average cost of textbooks per student. The Student PIRGs also point out that recent emphasis on e-textbooks does not always save students money. Even though the book costs less up-front, the student will not recover any of the cost through resale. Another publishing industry practice that has been highly criticized is "bundling", or shrink-wrapping supplemental items into
33735-889: The resale of textbooks on the used market, with publishers only earning profits on sales of new textbooks. According to the GAO study published July 2005: Following closely behind annual increases in tuition and fees at postsecondary institutions, college textbook and supply prices have risen at twice the rate of annual inflation over the last two decades. Rising at an average of 6 percent each year since academic year 1987–1988, compared with overall average price increases of 3 percent per year, college textbook and supply prices trailed tuition and fee increases, which averaged 7 percent per year. Since December 1986, textbook and supply prices have nearly tripled, increasing by 186 percent, while tuition and fees increased by 240 percent and overall prices grew by 72 percent. While increases in textbook and supply prices have followed increases in tuition and fees,
33930-424: The respective companies to continue to operate. Students can also sell or trade textbooks among themselves. After completing a course, sellers will often seek out members of the next enrolling class, people who are likely to be interested in purchasing the required books. This may be done by posting flyers to advertise the sale of the books or simply soliciting individuals who are shopping in the college bookstore for
34125-536: The resulting growth of schooling in Europe led to the printing of many more textbooks for children. Textbooks have been the primary teaching instrument for most children since the 19th century. Two textbooks of historical significance in United States schooling were the 18th century New England Primer and the 19th century McGuffey Readers . Recent technological advances have changed the way people interact with textbooks. Online and digital materials are making it increasingly easy for students to access materials other than
34320-418: The sale of used books , and would make that entire industry illegal. Another alternative to save money and obtaining the materials you are required are e-textbooks. The article "E books rewrite the rules of education" states that, alternately to spending a lot of money on textbooks, you can purchase an e-textbook at a small amount of the cost. With the growth of digital applications for iPhone, and gadgets like
34515-419: The sale of used books. The concept is not unlike the limited licensing approach for computer software, which places rigid restrictions on resale and reproduction. The intent is to make users understand that the content of any textbook is the intellectual property of the author and/or the publisher, and that as such, subject to copyright. Obviously, this idea is completely opposed to the millennia-old tradition of
34710-571: The same fixed pattern; it is a proportional notation, in the sense that each note value is equal to two or three times the shorter value, or half or a third of the longer value. This same notation, transformed through various extensions and improvements during the Renaissance, forms the basis for rhythmic notation in European classical music today. D'Erlanger divulges that the Arabic music scale
34905-510: The same titles. Many larger schools have independent websites set up for the purpose of facilitating such trade. These often operate much like digital classified ads, enabling students to list their items for sale and browse for those they wish to acquire. Also, at the US Air Force Academy , it is possible to e-mail entire specific classes, allowing for an extensive network of textbook sales to exist. Online marketplaces are one of
35100-553: The second half, rock music did the same. Jazz is an American musical artform that originated in the beginning of the 20th century, in African American communities in the Southern United States from a confluence of African and European music traditions. The style's West African pedigree is evident in its use of blue notes , improvisation , polyrhythms , syncopation , and the swung note . Rock music
35295-538: The sonority of intervals that vary widely in different cultures and over the ages. Consonance (or concord) is the quality of an interval or chord that seems stable and complete in itself. Dissonance (or discord) is the opposite in that it feels incomplete and "wants to" resolve to a consonant interval. Dissonant intervals seem to clash. Consonant intervals seem to sound comfortable together. Commonly, perfect fourths, fifths, and octaves and all major and minor thirds and sixths are considered consonant. All others are dissonant to
35490-632: The southern states, is largely devotional; the majority of the songs are addressed to the Hindu deities. There are songs emphasizing love and other social issues. Indonesian music has been formed since the Bronze Age culture migrated to the Indonesian archipelago in the 2nd-3rd centuries BCE. Indonesian traditional music uses percussion instruments, especially kendang and gongs . Some of them developed elaborate and distinctive instruments, such as
35685-586: The standard musical notation is the lead sheet , which notates the melody, chords, lyrics (if it is a vocal piece), and structure of the music. Fake books are also used in jazz; they may consist of lead sheets or simply chord charts, which permit rhythm section members to improvise an accompaniment part to jazz songs. Scores and parts are also used in popular music and jazz, particularly in large ensembles such as jazz " big bands ." In popular music, guitarists and electric bass players often read music notated in tablature (often abbreviated as "tab"), which indicates
35880-409: The system known as equal temperament is most commonly used today because it is considered the most satisfactory compromise that allows instruments of fixed tuning (e.g. the piano) to sound acceptably in tune in all keys. Notes can be arranged in a variety of scales and modes . Western music theory generally divides the octave into a series of twelve pitches, called a chromatic scale , within which
36075-550: The texts, was in use for over 1,000 years." Much of Chinese music history and theory remains unclear. Chinese theory starts from numbers, the main musical numbers being twelve, five and eight. Twelve refers to the number of pitches on which the scales can be constructed. The Lüshi chunqiu from about 238 BCE recalls the legend of Ling Lun . On order of the Yellow Emperor , Ling Lun collected twelve bamboo lengths with thick and even nodes. Blowing on one of these like
36270-462: The timbre of a trumpet changes when a mute is inserted into the bell, the player changes their embouchure, or volume. A voice can change its timbre by the way the performer manipulates their vocal apparatus, (e.g. the shape of the vocal cavity or mouth). Musical notation frequently specifies alteration in timbre by changes in sounding technique, volume, accent, and other means. These are indicated variously by symbolic and verbal instruction. For example,
36465-463: The traditional Sufi dhikr rituals, are the closest contemporary music genre to ancient Egyptian music, having preserved many of its features, rhythms and instruments. The " Hurrian Hymn to Nikkal ", found on clay tablets in the ancient Syrian city of Ugarit , is the oldest surviving notated work of music, dating back to approximately 1400 BCE. Music was an important part of social and cultural life in ancient Greece , in fact it
36660-407: The traditional print textbook. Students now have access to electronic books ("e-books"), online tutoring systems and video lectures. An example of an e-book is Principles of Biology from Nature Publishing . Most notably, an increasing number of authors are avoiding commercial publishers and instead offering their textbooks under a creative commons or other open license. As in many industries,
36855-648: The two major types of online websites students can use to sell used textbooks. Online marketplaces may have an online auction format or may allow the student to list their books for a fixed price. In either case, the student must create the listing for each book themselves and wait for a buyer to order, making the use of marketplaces a more passive way of selling used textbooks. Unlike campus buyback and online book, students are unlikely to sell all their books to one buyer using online marketplaces, and will likely have to send out multiple books individually. Online book buyers buy textbooks, and sometimes other types of books, with
37050-403: The used book market. Each combination of a textbook and supplemental items receives a separate ISBN. A single textbook could therefore have dozens of ISBNs that denote different combinations of supplements packaged with that particular book. When a bookstore attempts to track down used copies of textbooks, they will search for the ISBN the course instructor orders, which will locate only a subset of
37245-744: The word dolce (sweetly) indicates a non-specific, but commonly understood soft and "sweet" timbre. Sul tasto instructs a string player to bow near or over the fingerboard to produce a less brilliant sound. Cuivre instructs a brass player to produce a forced and stridently brassy sound. Accent symbols like marcato (^) and dynamic indications ( pp ) can also indicate changes in timbre. In music, " dynamics " normally refers to variations of intensity or volume, as may be measured by physicists and audio engineers in decibels or phons . In music notation, however, dynamics are not treated as absolute values, but as relative ones. Because they are usually measured subjectively, there are factors besides amplitude that affect
37440-531: The world reveal details about the music they produced and potentially something of the musical theory that might have been used by their makers. In ancient and living cultures around the world, the deep and long roots of music theory are visible in instruments, oral traditions, and current music-making. Many cultures have also considered music theory in more formal ways such as written treatises and music notation . Practical and scholarly traditions overlap, as many practical treatises about music place themselves within
37635-418: Was a touchstone for other writings on music in medieval Europe. Boethius represented Classical authority on music during the Middle Ages, as the Greek writings on which he based his work were not read or translated by later Europeans until the 15th century. This treatise carefully maintains distance from the actual practice of music, focusing mostly on the mathematical proportions involved in tuning systems and on
37830-501: Was one of the main subjects taught to children. Musical education was considered important for the development of an individual's soul. Musicians and singers played a prominent role in Greek theater , and those who received a musical education were seen as nobles and in perfect harmony (as can be read in the Republic, Plato ). Mixed gender choruses performed for entertainment, celebration, and spiritual ceremonies. Instruments included
38025-403: Was to offer the open textbook free online, and then sell ancillary products that students are likely to buy if prices are reasonable – print copies, study guides, ePub , .Mobi ( Kindle ), PDF download, etc. Flat World Knowledge compensates its authors with royalties on these sales. With the generated revenue Flat World Knowledge funded high-quality publishing activities with a goal of making
