83-406: The app was removed from the iOS and Android app stores on December 14th, 2022. DropMix comes in a core package that includes 60 NFC-equipped cards, each representing a different song, and an electronic game board with five marked spaces; the game also requires a mobile device that can communicate with the board through Bluetooth through a free app. Additional cards enabling new music samples within

166-444: A tonic or tonic chord , which provides a subjective sense of arrival and rest, and also has a unique relationship to the other pitches of the same key, their corresponding chords, and pitches and chords outside the key. Notes and chords other than the tonic in a piece create varying degrees of tension, resolved when the tonic note or chord returns. The key may be in the major or minor mode, though musicians assume major when this

249-416: A whole tone lower than written. Likewise, the horn , normally in the key of F, sounds notes a perfect fifth lower than written. Similarly, some instruments are "built" in a certain key. For example, a brass instrument built in B ♭ plays a fundamental note of B ♭ , and can play notes in the harmonic series starting on B ♭ without using valves, fingerholes, or slides to alter

332-535: A wolf fifth , the key on the lowest note of the fifth sounds dramatically different from other keys (and is often avoided). In Pythagorean tuning on C (C, E+, G: 4, 5, 6), the major triad on C is just while the major triad on E ♯ +++ (F ♮ ) is noticeably out of tune (E ♯ +++, A+, C: 4 + 1 ⁄ 8 , 5, 6) due to E ♯ +++ (521.44 cents) being a Pythagorean comma (23.46 cents) larger sharp compared to F ♮ . Music using equal temperament lacks key coloration because all keys have

415-408: A card on a space with a matching color will cause that track sample to be used as part of the app's current mix; non-matching placement will have no effect. In addition, each card has a power level marking from one to three. In the app, this represents how much an influence the sample will have on the ongoing mix in terms of its speed, key or length. A card with 3 power will have a pronounced impact on

498-454: A certain key, or have their music written in a certain key. Instruments that do not play in the key of C are known as transposing instruments . The most common kind of clarinet , for example, is said to play in the key of B ♭ . This means that a scale written in C major in sheet music actually sounds as a B ♭ major scale when played on the B-flat clarinet—that is, notes sound

581-412: A different key; if the modulation is brief, it may not involve a change of key signature, being indicated instead with accidentals . Occasionally, a piece in a mode such as Mixolydian or Dorian is written with a major or minor key signature appropriate to the tonic, and accidentals throughout the piece. Pieces in modes not corresponding to major or minor keys may sometimes be referred to as being in

664-408: A feature that allows multiple interpretations of key (usually a diatonic set as pitch source) is accompanied by other, more precise evidence in support of each possible interpretation (such as the use of one note as the root of the initiating harmony and persistent use of another note as pitch of melodic resolution and root of the final harmony of each phrase)." Certain musical instruments play in

747-505: 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

830-650: 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

913-723: 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

996-488: 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

1079-512: 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

1162-779: 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

1245-469: 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

1328-457: A tone comprises. Timbre is principally determined by two things: (1) 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,

1411-678: 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

1494-399: 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

1577-410: 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

1660-799: 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

1743-453: 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

1826-402: 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

1909-464: 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

1992-591: Is derived from the Greek music scale, and that Arabic music is connected to certain features of Arabic culture, such as astrology. 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

2075-399: Is frequently concerned with describing how musicians and composers make music, including tuning systems and composition methods among other topics. Because of 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

2158-466: Is not specified; for example "This piece is in C" implies that the key of the piece is C major. Popular songs and classical music from the common practice period are usually in one key. Longer pieces in the classical repertoire may have sections in contrasting keys . Key changes within a section or movement are known as modulation . Methods that establish the key for a particular piece can be complicated to explain and vary over music history. However,

2241-419: Is often referred to as "separated" or "detached" rather than having a defined or numbered amount by which to reduce the notated duration. Violin players use a variety of techniques to perform different qualities of staccato. The manner in which a performer decides to execute a given articulation is usually based on the context of the piece or phrase, but many articulation symbols and verbal instructions depend on

2324-427: Is one component of music that has as yet, no standardized nomenclature. It has been called "... 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

2407-521: Is produced by the sequential arrangement of sounds and silences in time. Meter measures music in regular pulse groupings, called measures or bars . 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

2490-554: 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

2573-434: Is thus usually thought of as in a specific mode rather than a key. Languages other than English may use other key naming systems . People sometimes confuse key with scale . A scale is an ordered set of notes typically used in a key, while the key is the "center of gravity" established by particular chord progressions . Cadences are particularly important in the establishment of key. Even cadences that do not include

2656-479: The Quadrivium liberal arts university curriculum, that was common in medieval Europe , was an abstract system of proportions that was carefully studied at 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

A key relationship is the relationship between keys, measured by common tone and nearness on the circle of fifths . See closely related key . The key usually identifies the tonic note and/or chord: the note and/or major or minor triad that represents

2905-471: The key of a piece is the group of pitches, or scale , that forms the basis of a musical composition in Western classical music , art music , and pop music . Tonality (from "Tonic") or key: Music which uses the notes of a particular scale is said to be "in the key of" that scale or in the tonality of that scale. A particular key features a tonic note and its corresponding chords , also called

2988-572: The "horizontal" aspect. Counterpoint , which refers to 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

At any time, players can save the current mix to the app and share that through social media. Cards are organized into "playlists." Each playlist contains 15 cards. The Starter Pack comes with the board and 4 playlists. Dropmix cards can be purchased in one of two forms: Playlist Packs and Discover Packs. With Playlist Packs, you will receive 16 cards. 15 of

3154-601: The Western popular music of the 20th century, pieces always begin and end in the same key, even if (as in some Romantic-era music) the key is deliberately left ambiguous at first. Some arrangements of popular songs, however, modulate sometime during the song (often in a repeat of the final chorus ) and thus end in a different key. This is an example of modulation . In rock and popular music some pieces change back and forth, or modulate, between two keys. Examples of this include Fleetwood Mac 's " Dreams " and The Rolling Stones ' " Under My Thumb ". "This phenomenon occurs when

3237-654: 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

3320-454: The app can be purchased separately as booster packs, the price depending on the number of cards available. Each card is keyed to at least one of four colors, the colors representative of the instrument that can be sampled from that song. For example, yellow represents vocal tracks, while blue represents drum tracks. The board's five spaces are similarly marked by color, with three of the five spaces accepting cards of two different colors. Placing

Taking turns, each player plays a card by color as instructed by the app, but may only play a card of greater power than one already present (if such is the case). If they can, they earn points; if they are unable to, they hit a button on the game board which has

3652-470: 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

3735-415: The chords most often used in a piece in a particular key are those that contain the notes in the corresponding scale , and conventional progressions of these chords, particularly cadences , orient the listener around the tonic. The key signature is not always a reliable guide to the key of a written piece. It does not discriminate between a major key and its relative minor; the piece may modulate to

3818-407: The current mix compared to a card with a power of 1. Cards can be played on top of other cards or removed from the board, the app playing the sample only from the top-most card. Special white cards can be played on any space, which can cause an entire change in the speed and key of the ongoing loop. The app provides four game modes as of August 2018. "Freestyle" mode lets players simply try to combine

3901-402: 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,

3984-657: 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

4067-402: The final point of rest for a piece, or the focal point of a section. Though the key of a piece may be named in the title (e.g., Symphony in C major), or inferred from the key signature , the establishment of key is brought about via functional harmony , a sequence of chords leading to one or more cadences , and/or melodic motion (such as movement from the leading-tone to the tonic). For example,

4150-521: 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 )

4233-406: 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

4316-1002: 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

4399-426: 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

4482-479: The key of G includes the following pitches: G, A, B, C, D, E, and F ♯ ; and its corresponding tonic chord is G—B—D. Most often at the beginning and end of traditional pieces during the common practice period, the tonic, sometimes with its corresponding tonic chord, begins and ends a piece in a designated key. A key may be major or minor. Music can be described as being in the Dorian mode , or Phrygian , etc., and

4565-420: The key of the tonic. A piece using some other type of harmony , resolving e.g. to A, might be described as "in A" to indicate that A is the tonal center of the piece. An instrument "in a key", is an unrelated usage that means the pitches considered "natural" for that instrument. For example, modern trumpets are usually in the key of B ♭ , since the notes produced without using the valves correspond to

4648-481: 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

4731-419: The length of the vibrating column of air. An instrument built in a certain key often, but not always, uses music written in the same key (see trombone for an exception). However, some instruments, such as the diatonic harmonica and the harp , are in fact designed to play in only one key at a time: accidentals are difficult or impossible to play. The highland bagpipes are built in B ♭ major, though

4814-428: 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 the world reveal details about the music they produced and potentially something of

4897-438: 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

4980-420: The music is written in D major with implied accidentals. In Western musical composition, the key of a piece has important ramifications for its composition: Key coloration is the difference between the intervals of different keys in a single non-equal tempered tuning, and the overall sound and "feel" of the key created by the tuning of its intervals. Historical irregular musical temperaments usually have

5063-572: 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,

5146-447: 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

5229-399: 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

5312-425: The narrowest fifths between the diatonic notes ("naturals") producing purer thirds , and wider fifths among the chromatic notes ("sharps and flats"). Each key then has a slightly different intonation , hence different keys have distinct characters. Such "key coloration" was an essential part of much eighteenth- and nineteenth-century music and was described in treatises of the period. For example, in tunings with

5395-497: 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

5478-444: 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

5561-598: The performer's technique. The timbre of most instruments can be changed by employing different techniques while playing. For example, 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,

5644-584: 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

5727-477: 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

5810-404: 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

5893-457: 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

5976-408: 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

6059-571: 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

6142-438: The same pattern of intonation, differing only in pitch. Music theory 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 );

6225-402: The second is learning scholars' views on music from antiquity to 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

6308-538: 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

6391-409: 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

6474-552: 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

6557-423: The tonic note or triad, such as half cadences and deceptive cadences , serve to establish key because those chord sequences imply a unique diatonic context . Short pieces may stay in a single key throughout. A typical pattern for a simple song might be as follows: a phrase ends with a cadence on the tonic, a second phrase ends with a half cadence, then a final, longer, phrase ends with an authentic cadence on

6640-492: The tonic. More elaborate pieces may establish the main key, then modulate to another key, or a series of keys, then back to the original key. In the Baroque it was common to repeat an entire phrase of music, called a ritornello , in each key once it was established. In Classical sonata form , the second key was typically marked with a contrasting theme . Another key may be treated as a temporary tonic, called tonicization . In common practice period compositions, and most of

6723-745: 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

6806-419: 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
