218-478: A back-formation of accord in the original sense of agreement and later, harmonious sound . A sequence of chords is known as a chord progression or harmonic progression. These are frequently used in Western music. A chord progression "aims for a definite goal" of establishing (or contradicting) a tonality founded on a key, root or tonic chord. The study of harmony involves chords and chord progressions and

327-414: A degree symbol (e.g., vii indicates a diminished seventh chord built on the seventh scale degree; in the key of C major, this chord would be B diminished seventh, which consists of the notes B, D, F and A ♭ ). Roman numerals can also be used in stringed instrument notation to indicate the position or string to play. In some string music, the string on which it is suggested that the performer play

436-432: A major or minor scale ) in which one tone (the tonic) becomes the central point for the remaining tones. The other tones in a tonal piece are all defined in terms of their relationship to the tonic. In tonality, the tonic (tonal center) is the tone of complete relaxation and stability, the target toward which other tones lead. The cadence (a rest point) in which the dominant chord or dominant seventh chord resolves to

654-478: A C Major cadence (coming to rest point) or a deceptive cadence to an A minor chord). "The larger portion of the world's folk and art music can be categorized as tonal," as long as the definition is as follows: "Tonal music gives priority to a single tone or tonic. In this kind of music all the constituent tones and resulting tonal relationships are heard and identified relative to their tonic". In this sense, "All harmonic idioms in popular music are tonal, and none

872-463: A bass note, the figure is assumed to be 3 , which calls for a third and a fifth above the bass note (i.e., a root position triad). In the 2010s, some classical musicians who specialize in music from the Baroque era can still perform chords using figured bass notation; in many cases, however, the chord-playing performers read a fully notated accompaniment that has been prepared for the piece by

981-401: A chord may be understood as such even when all its notes are not simultaneously audible, there has been some academic discussion regarding the point at which a group of notes may be called a chord . Jean-Jacques Nattiez explains that, "We can encounter 'pure chords' in a musical work", such as in the "Promenade" of Modest Mussorgsky 's Pictures at an Exhibition but, "often, we must go from

1090-481: A chord name and the corresponding symbol are typically composed of one or more parts. In these genres, chord-playing musicians in the rhythm section (e.g., electric guitar , acoustic guitar , piano , Hammond organ , etc.) typically improvise the specific " voicing " of each chord from a song's chord progression by interpreting the written chord symbols appearing in the lead sheet or fake book . Normally, these chord symbols include: Chord qualities are related with

1199-619: A close and begins the next." From this point of view, twelve-tone music could be regarded "either as the natural and inevitable culmination of an organic motivic process ( Webern ) or as a historical Aufhebung ( Adorno ), the dialectical synthesis of late Romantic motivic practice on the one hand with a musical sublimation of tonality as pure system on the other". In another sense, tonality means any rational and self-contained theoretical arrangement of musical pitches, existing prior to any concrete embodiment in music. For example, "Sainsbury, who had Choron translated into English in 1825, rendered

1308-430: A composed-out triad, but rather a diverging-converging pair of chromatic lines moving from a unison A to an octave E ♭ and back to a unison A again, providing a framing "deep structure" based on a tritone relationship that nevertheless is not analogous to a tonic-dominant axis, but rather remains within the single functional domain of the tonic, A. To distinguish this species of tonality (found also, for example, in

1417-467: A dominant in relation to D, or [REDACTED] (where the caret designates a scale degree) in G major rather than a mere acoustical frequency, in this case 440 Hz". The word tonality is sometimes used as a synonym for " key ", as in "the C-minor tonality of Beethoven's Fifth Symphony ". In some languages, indeed, the word for "key" and that for "tonality" are the same, e.g. French tonalité . There

1526-454: A dyad with a perfect fifth has no third, so it does not sound major or minor; a composer who ends a section on a perfect fifth could subsequently add the missing third. Another example is a dyad outlining the tritone , such as the notes C and F# in C Major. This dyad could be heard as implying a D7 chord (resolving to G Major) or as implying a C diminished chord (resolving to Db Major). In unaccompanied duos for two instruments, such as flute duos,

1744-579: A large part in the sound of the chord, and sometimes of the selection of the chord that follows. A chord containing tritones is called tritonic ; one without tritones is atritonic . Harmonic tritones are an important part of dominant seventh chords , giving their sound a characteristic tension, and making the tritone interval likely to move in certain stereotypical ways to the following chord. Tritones are also present in diminished seventh and half-diminished chords . A chord containing semitones , whether appearing as minor seconds or major sevenths ,

1853-425: A major triad with an added minor seventh above the root. To achieve this in minor keys, the seventh scale degree must be raised to create a major triad on the dominant. David Cope considers key, consonance and dissonance (relaxation and tension, respectively), and hierarchical relationships the three most basic concepts in tonality. Carl Dahlhaus lists the characteristic schemata of tonal harmony, "typified in

1962-453: A minor chord, or using the major key, ii, iii and vi representing typical diatonic minor triads); other writers (e.g., Schoenberg ) use upper case Roman numerals for both major and minor triads. Some writers use upper-case Roman numerals to indicate the chord is diatonic in the major scale, and lower-case Roman numerals to indicate that the chord is diatonic in the minor scale. Diminished triads may be represented by lower-case Roman numerals with

2071-441: A minor ninth, a sharp ninth, a diminished fifth, or an augmented fifth. Some write this as C , which assumes also the minor ninth, diminished fifth and augmented fifth. The augmented ninth is often referred to in blues and jazz as a blue note , being enharmonically equivalent to the minor third or tenth. When superscripted numerals are used the different numbers may be listed horizontally or vertically. Tonality Tonality

2180-463: A reduced emphasis on tonal function. These genres are often expressed in two parts—a bass line doubled in fifths, and a single vocal part. Power chord technique was often allied with modal procedure". Much jazz is tonal, but "functional tonality in jazz has different properties than that of common-practice classical music. These properties are represented by a unique set of rules dictating the unfolding of harmonic function, voice-leading conventions, and

2289-412: A referential tonic. In a slightly different sense to the one above, tonality can also be used to refer to musical phenomena perceived or preinterpreted in terms of the categories of tonal theories. This is a psychophysical sense, where for example "listeners tend to hear a given pitch as, for instance, an A above middle C, an augmented 4th above E ♭ , the minor 3rd in an F ♯ minor triad,

2398-809: A resurgence in the Post-Romantic and Impressionistic period. The Romantic period , the 19th century, featured increased chromaticism . Composers began to use secondary dominants in the Baroque, and they became common in the Romantic period. Many contemporary popular Western genres continue to rely on simple diatonic harmony, though far from universally: notable exceptions include the music of film scores , which often use chromatic, atonal or post-tonal harmony, and modern jazz (especially c.  1960 ), in which chords may include up to seven notes (and occasionally more). When referring to chords that do not function as harmony, such as in atonal music,

2507-469: A sequence of notes separated by intervals of roughly the same size. Chords can be classified into different categories by this size: These terms can become ambiguous when dealing with non- diatonic scales , such as the pentatonic or chromatic scales . The use of accidentals can also complicate the terminology. For example, the chord B ♯ –E–A ♭ appears to be quartal, as a series of diminished fourths (B ♯ –E and E–A ♭ ), but it

2616-533: A textual given to a more abstract representation of the chords being used", as in Claude Debussy 's Première arabesque . In the medieval era, early Christian hymns featured organum (which used the simultaneous perfect intervals of a fourth, a fifth, and an octave ), with chord progressions and harmony - an incidental result of the emphasis on melodic lines during the medieval and then Renaissance (15th to 17th centuries). The Baroque period,

2725-430: A tone center, that non-triadic harmonic formations may be made to function as referential elements, and that the assumption of a twelve-tone complex does not preclude the existence of tone centers". For the composer and theorist George Perle , tonality is not "a matter of 'tone-centeredness', whether based on a 'natural' hierarchy of pitches derived from the overtone series or an 'artificial' pre compositional ordering of

2834-428: A tone center, that non-triadic harmonic formations may be made to function as referential elements, and that the assumption of a twelve-tone complex does not preclude the existence of tone centers". For the composer and theorist George Perle , tonality is not "a matter of 'tone-centeredness', whether based on a 'natural' hierarchy of pitches derived from the overtone series or an 'artificial' pre compositional ordering of

2943-451: A tonic. In the 20th century, music that no longer conformed to the strict definition of common-practice tonality could nevertheless still involve musical phenomena (harmonies, cadential formulae, harmonic progressions, melodic gestures, formal categories) arranged or understood in relation to a referential tonic. For example, the closing bars of the first movement of Béla Bartók 's Music for Strings, Percussion and Celesta do not involve

3052-444: A uniformity which provided few guides for either composition or listening." Tonality may be considered generally, with no restrictions on the date or place the music was produced, and little restriction on the materials and methods used. This definition includes pre-17th century western music, as well as much non-western music. By the middle of the 20th century, it had become "evident that triadic structure does not necessarily generate

3161-452: Is enharmonically equivalent to (and sonically indistinguishable from) the tertian chord C–E–G ♯ , which is a series of major thirds (C–E and E–G ♯ ). The notes of a chord form intervals with each of the other notes of the chord in combination. A 3-note chord has 3 of these harmonic intervals, a 4-note chord has 6, a 5-note chord has 10, a 6-note chord has 15. The absence, presence, and placement of certain key intervals plays

3270-539: Is a diminished fifth or an augmented fifth. In a pop or rock context, however, "C" and "Cm" would almost always be played as triads, with no sevenths. In pop and rock, in the relatively less common cases where songwriters wish a dominant seventh, major seventh, or minor seventh chord, they indicate this explicitly with the indications "C ", "C " or "Cm ". Within the diatonic scale , every chord has certain characteristics, which include: Two-note combinations, whether referred to as chords or intervals, are called dyads . In

3379-404: Is a loose assortment of ideas associated with the term. "Tonal harmonies must always include the third of the chord". In major and minor harmonies, the perfect fifth is often implied and understood by the listener even if it is not present. To function as a tonic, a chord must be either a major or a minor triad. Dominant function requires a major-quality triad with a root a perfect fifth above

3488-476: Is all these things. A viewpoint held by many theorists since the third quarter of the 19th century, following the publication in 1862 of the first edition of Helmholtz's On the Sensation of Tone , holds that diatonic scales and tonality arise from natural overtones. Rudolph Réti differentiates between harmonic tonality of the traditional kind found in homophony , and melodic tonality, as in monophony . In

3597-452: Is called hemitonic ; one without semitones is anhemitonic . Harmonic semitones are an important part of major seventh chords , giving their sound a characteristic high tension, and making the harmonic semitone likely to move in certain stereotypical ways to the following chord. A chord containing major sevenths but no minor seconds is much less harsh in sound than one containing minor seconds as well. Other chords of interest might include

3706-402: Is called a chord progression . One example of a widely used chord progression in Western traditional music and blues is the 12 bar blues progression . Although any chord may in principle be followed by any other chord, certain patterns of chords are more common in Western music, and some patterns have been accepted as establishing the key ( tonic note ) in common-practice harmony —notably

3815-599: Is different from Wikidata All article disambiguation pages All disambiguation pages Chord (music) In tonal Western classical music (music with a tonic key or "home key"), the most frequently encountered chords are triads , so called because they consist of three distinct notes: the root note, and intervals of a third and a fifth above the root note. Chords with more than three notes include added tone chords , extended chords and tone clusters , which are used in contemporary classical music , jazz and almost any other genre. A series of chords

3924-441: Is often taken as the minimum number of notes that form a definite chord. Hence, Andrew Surmani , for example, states, "When three or more notes are sounded together, the combination is called a chord." George T. Jones agrees: "Two tones sounding together are usually termed an interval , while three or more tones are called a chord ." According to Monath, "a chord is a combination of three or more tones sounded simultaneously", and

4033-467: Is rendered so in the seminal New Grove article "Mode", etc.). Therefore, two different German words "Tonart" and "Tonalität" have sometimes been translated as "tonality" although they are not the same words in German. In 1882, Hugo Riemann defined the term Tonalität specifically to include chromatic as well as diatonic relationships to a tonic, in contrast to the usual diatonic concept of Tonart . In

4142-400: Is the dominant seventh chord built on the fifth scale degree; in the key of C Major, this would be a G dominant seventh chord, or G7 chord, which contains the pitches G, B, D and F. This dominant seventh chord contains a dissonant tritone interval between the notes B and F. In pop music, the listener will expect this tritone to be resolved to a consonant, stable chord (in this case, typically

4251-401: Is the arrangement of pitches and/or chords of a musical work in a hierarchy of perceived relations, stabilities, attractions, and directionality. In this hierarchy the single pitch or triad with the greatest stability is called the tonic . The root of the tonic triad forms the name given to the key , so in the key of C major the tone C can be both the tonic of the scale and the root of

4360-418: Is when G (G–B–D–F–A ♭ –C ♯ ) is formed from G major (G–B–D) and D ♭ major (D ♭ –F–A ♭ ). A nonchord tone is a dissonant or unstable tone that lies outside the chord currently heard, though often resolving to a chord tone. In the key of C major , the first degree of the scale, called the tonic , is the note C itself. A C major chord, the major triad built on

4469-501: Is without function". However, "within the continuing hegemony of tonality there is evidence for a relatively separate tradition of genuine folk musics, which do not operate completely or even mainly according to the assumptions or rules of tonality. … throughout the reign of tonality there seem to have existed subterranean folk musical traditions organized on principles different from tonality, and often modal: Celtic songs and blues are obvious examples". According to Allan Moore, "part of

4578-464: The Triads, also called triadic chords , are tertian chords with three notes. The four basic triads are described below. Seventh chords are tertian chords, constructed by adding a fourth note to a triad, at the interval of a third above the fifth of the chord. This creates the interval of a seventh above the root of the chord, the next natural step in composing tertian chords. The seventh chord built on

According to Choron, this pattern, which he called tonalité moderne , distinguished modern music's harmonic organization from that of earlier [pre 17th century] music, including tonalité des Grecs (ancient Greek modes) and tonalité ecclésiastique (plainchant). According to Choron,

4905-418: The qualities of the component intervals that define the chord. The main chord qualities are: The symbols used for notating chords are: The table below lists common chord types, their symbols, and their components. The basic function of chord symbols is to eliminate the need to write out sheet music. The modern jazz player has extensive knowledge of the chordal functions and can mostly play music by reading

5014-651: The resolution of a dominant chord to a tonic chord . To describe this, Western music theory has developed the practice of numbering chords using Roman numerals to represent the number of diatonic steps up from the tonic note of the scale . Common ways of notating or representing chords in Western music (other than conventional staff notation ) include Roman numerals , the Nashville Number System , figured bass , chord letters (sometimes used in modern musicology ), and chord charts . The English word chord derives from Middle English cord ,

This sense also applies to the tonic/dominant/subdominant harmonic constellations in the theories of Jean-Philippe Rameau as well as the 144 basic transformations of twelve-tone technique . By the middle of the 20th century, it had become "evident that triadic structure does not necessarily generate

5232-418: The 14th century, Italian musicologists Marco Mangani and Daniele Sabaino in the late Renaissance music, and so on. The wide usage of "tonality" and "tonal" has been supported by several other musicologists (of diverse provenance). A possible reason for this broader usage of terms "tonality" and "tonal" is the attempt to translate German "Tonart" as "tonality" and "Tonarten-" prefix as "tonal" (for example, it

5341-506: The 17th and 18th centuries, began to feature the major and minor scale based tonal system and harmony, including chord progressions and circle progressions . It was in the Baroque period that the accompaniment of melodies with chords was developed, as in figured bass , and the familiar cadences (perfect authentic, etc.). In the Renaissance, certain dissonant sonorities that suggest the dominant seventh occurred with frequency. In

5450-442: The 1830s and 1840s, finally codifying his theory of tonality in 1844, in his Traité complet de la théorie et de la pratique de l'harmonie . Fétis saw tonalité moderne as the historically evolving phenomenon with three stages: tonality of ordre transitonique ("transitonic order"), of ordre pluritonique ("pluritonic order") and, finally, ordre omnitonique ("omnitonic order"). The "transitonic" phase of tonality he connected with

5559-467: The 2000s may practice or avoid any sort of tonality—but harmony in almost all Western popular music remains tonal. Harmony in jazz includes many but not all tonal characteristics of the European common practice period , usually known as "classical music". "All harmonic idioms in popular music are tonal, and none is without function ." Tonality is an organized system of tones (e.g., the tones of

5668-513: The Baroque period, the dominant seventh proper was introduced and was in constant use in the Classical and Romantic periods . The leading-tone seventh appeared in the Baroque period and remains in use. Composers began to use nondominant seventh chords in the Baroque period. They became frequent in the Classical period, gave way to altered dominants in the Romantic period, and underwent

5777-453: The C major chord: Further, a four-note chord can be inverted to four different positions by the same method as triadic inversion. For example, a G chord can be in root position (G as bass note); first inversion (B as bass note); second inversion (D as bass note); or third inversion (F as bass note). Where guitar chords are concerned, the term "inversion" is used slightly differently; to refer to stock fingering "shapes". Many chords are

5886-418: The Western plainchant. Fétis believed that tonality, tonalité moderne , was entirely cultural, saying, "For the elements of music, nature provides nothing but a multitude of tones differing in pitch, duration, and intensity by the greater or least degree ... The conception of the relationships that exist among them is awakened in the intellect, and, by the action of sensitivity on the one hand, and will on

5995-404: The affiliated tonic and containing the leading tone of the key. This dominant triad must be preceded by a chord progression that establishes the dominant as the penultimate goal of a motion that is completed by moving on to the tonic. In this final dominant-to-tonic progression, the leading tone normally ascends by semitone motion to the tonic scale degree. A dominant seventh chord always consist of

6104-465: The analysis. Roman numeral analysis indicates the root of the chord as a scale degree within a particular major key as follows. In the harmony of Western art music, a chord is in root position when the tonic note is the lowest in the chord (the bass note ), and the other notes are above it. When the lowest note is not the tonic, the chord is inverted . Chords that have many constituent notes can have many different inverted positions as shown below for

6213-489: The beginnings of this modern tonality are found in the music of Claudio Monteverdi around the year 1595, but it was more than a century later that the full application of tonal harmony finally supplanted the older reliance on the melodic orientation of the church modes, in the music of the Neapolitan School —most especially that of Francesco Durante . François-Joseph Fétis developed the concept of tonalité in

6322-465: The chord are always determined by the symbols shown above. The root cannot be so altered without changing the name of the chord, while the third cannot be altered without altering the chord's quality. Nevertheless, the fifth, ninth, eleventh and thirteenth may all be chromatically altered by accidentals. These are noted alongside the altered element. Accidentals are most often used with dominant seventh chords. Altered dominant seventh chords (C ) may have

6431-512: The chord symbols only. Advanced chords are common especially in modern jazz. Altered 9ths, 11ths and 5ths are not common in pop music. In jazz, a chord chart is used by comping musicians ( jazz guitar , jazz piano , Hammond organ ) to improvise a chordal accompaniment and to play improvised solos. Jazz bass players improvise a bassline from a chord chart. Chord charts are used by horn players and other solo instruments to guide their solo improvisations. Interpretation of chord symbols depends on

His examples are ancient Jewish and Gregorian chant and other Eastern music, and he points out how these melodies often may be interrupted at any point and returned to

6649-602: The common practice period. Major-minor tonality is also called harmonic tonality (in the title of Carl Dahlhaus, translating the German harmonische Tonalität ), diatonic tonality , common practice tonality , functional tonality , or just tonality . At least eight distinct senses of the word "tonality" (and corresponding adjective, "tonal"), some mutually exclusive, have been identified. The word tonality may describe any systematic organization of pitch phenomena in any music at all, including pre-17th century western music as well as much non-western music, such as music based on

The last of these progressions is characterized by "retrograde" harmonic motion. The consonance and dissonance of different intervals plays an important role in establishing

6867-477: The concept of "tonal types" to Renaissance sacred and paraliturgical polyphony. Cristle Collins Judd (the author of many articles and a thesis dedicated to the early pitch systems) found "tonalities" in this sense in motets of Josquin des Prez . Judd also wrote of "chant-based tonality", meaning "tonal" polyphonic compositions based on plainchant. Peter Lefferts found "tonal types" in the French polyphonic chanson of

6976-408: The context of a specific section in a piece of music, dyads can be heard as chords if they contain the most important notes of a certain chord. For example, in a piece in C Major, after a section of tonic C Major chords, a dyad containing the notes B and D sounds to most listeners as a first inversion G Major chord. Other dyads are more ambiguous, an aspect that composers can use creatively. For example,

7085-428: The date when modern tonality began, and the cadence began to be seen as the definitive way that a tonality is established in a work of music. In the music of some late-Romantic or post-Romantic composers such as Richard Wagner , Hugo Wolf , Pyotr Ilyich Tchaikovsky , Anton Bruckner , Gustav Mahler , Richard Strauss , Alexander Scriabin , and others, we find a variety of harmonic and linear procedures that have

7194-406: The distances between the tones are called intervals. However, sonorities of two pitches, or even single-note melodies, are commonly heard as implying chords. A simple example of two notes being interpreted as a chord is when the root and third are played but the fifth is omitted. In the key of C major, if the music stops on the two notes G and B, most listeners hear this as a G major chord. Since

7303-456: The early 20th century, the tonality that had prevailed since the 17th century was seen to have reached a crisis or break down point. Because of the "...increased use of the ambiguous chords, the less probable harmonic progressions, and the more unusual melodic and rhythmic inflections," the syntax of functional harmony loosened to the point where, "At best, the felt probabilities of the style system had become obscure; at worst, they were approaching

7412-612: The effect of weakening functional tonality. These procedures may produce a suspension of tonality or may create a sense of tonal ambiguity, even to the point that at times the sense of tonality is completely lost. Schoenberg described this kind of tonality (with references to the music of Wagner, Mahler, and himself, amongst others) as "aufgehobene Tonalität" and "schwebende Tonalität", usually rendered in English as "suspended" ("not in effect", "cancelled") tonality and "fluctuating" ("suspended", "not yet decided") tonality, respectively. In

7521-410: The emergence of the common practice period around 1600, with the difference between tonalité ancienne (before 1600) and tonalité moderne (after 1600) being one of emphasis rather than of kind. In a general way, tonality can refer to a wide variety of musical phenomena (harmonies, cadential formulae, harmonic progressions, melodic gestures, formal categories) as arranged or understood in relation to

7630-541: The fifth step of the scale (the dominant seventh) is the only dominant seventh chord available in the major scale: it contains all three notes of the diminished triad of the seventh and is frequently used as a stronger substitute for it. There are various types of seventh chords depending on the quality of both the chord and the seventh added. In chord notation the chord type is sometimes superscripted and sometimes not (e.g., Dm7, Dm , and D are all identical). Extended chords are triads with further tertian notes added beyond

7739-633: The first occurrence of tonalité as a 'system of modes' before matching it with the neologism 'tonality'. While tonality qua system constitutes a theoretical (and thus imaginative) abstraction from actual music, it is often hypostatized in musicological discourse, converted from a theoretical structure into a musical reality. In this sense, it is understood as a Platonic form or prediscursive musical essence that suffuses music with intelligible sense, which exists before its concrete embodiment in music, and can thus be theorized and discussed apart from actual musical contexts". To contrast with " modal " and " atonal ",

7848-433: The genre of music being played. In jazz from the bebop era or later, major and minor chords are typically realized as seventh chords even if only "C" or "Cm" appear in the chart. In jazz charts, seventh chords are often realized with upper extensions , such as the ninth, sharp eleventh, and thirteenth, even if the chart only indicates "A ". In jazz, the root and fifth are often omitted from chord voicings , except when there

He argues that in the progression I–x–V–I (and all progressions), V–I is the only step "which as such produces the effect of tonality", and that all other chord successions, diatonic or not, being more or less similar to the tonic-dominant, are "the composer's free invention." He describes melodic tonality (the term coined independently and 10 years earlier by Estonian composer Jaan Soonvald ) as being "entirely different from

8066-637: The heritage of rock lies within common-practice tonality" but, because the leading-note /tonic relationship is "axiomatic to the definition of common-practice tonality", and a fundamental feature of rock music's identity is the absence of a diatonic leading tone, the harmonic practices of rock music, "while sharing many features with classical tonality, are nonetheless distinct". Power chords are especially problematic when trying to apply classical functional tonality to certain varieties of popular music. Genres such as heavy metal , new wave , punk rock , and grunge music "took power chords into new arenas, often with

8175-475: The introduction to a collection of essays dedicated to the concept and practice of tonality between 1900 and 1950 describe it generally as "the awareness of key in music". Harold Powers , in a series of articles, used terms "sixteenth-century tonalities" and "Renaissance tonality". He borrowed German "Tonartentyp" from Siegfried Hermelink  [ de ] , who related it to Palestrina, translated it into English as "tonal type", and systematically applied

8284-404: The key of a piece of classical Western music (recorded in audio data format) automatically. These methods are often based on a compressed representation of the pitch content in a 12-dimensional pitch-class profile (chromagram) and a subsequent procedure that finds the best match between this representation and one of the prototype vectors of the 24 minor and major keys. For implementation, often

8393-415: The late Monteverdi . He described his earliest example of tonalité moderne thus: "In the passage quoted here from Monteverdi's madrigal ( Cruda amarilli , mm. 9–19 and 24–30), one sees a tonality determined by the accord parfait [root position major chord] on the tonic, by the sixth chord assigned to the chords on the third and seventh degrees of the scale, by the optional choice of the accord parfait or

8502-523: The melodic and harmonic phenomena that spring from it out of our conformation and education." Fétis' Traité complet was very popular. In France alone the book was printed between 1844 and 1903 twenty times. The 1st edition was printed in Paris and Brussels in 1844, the 9th edition was printed in Paris in 1864, and the 20th edition was printed in Paris in 1903. In contrast, Hugo Riemann believed tonality, "affinities between tones" or Tonverwandtschaften ,

8611-479: The music of Barber , Berg , Bernstein , Britten , Fine , Hindemith , Poulenc , Prokofiev , and, especially, Stravinsky) from the stricter kind associated with the 18th century, some writers use the term " neotonality ", while others prefer to use the term centricity , and still others retain the term tonality , in its broader sense or use word combinations like extended tonality . In music information retrieval , techniques have been developed to determine

8720-457: The music publisher. Such a part, with fully written-out chords, is called a "realization" of the figured bass part. Chord letters are used by musicologists , music theorists and advanced university music students to analyze songs and pieces. Chord letters use upper-case and lower-case letters to indicate the roots of chords, followed by symbols that specify the chord quality. In most genres of popular music, including jazz , pop , and rock ,

8829-581: The note C (C–E–G), is referred to as the one chord of that key and notated in Roman numerals as I. The same C major chord can be found in other scales: it forms chord III in the key of A minor (A→B→C) and chord IV in the key of G major (G→A→B→C). This numbering indicates the chords's function . Many analysts use lower-case Roman numerals to indicate minor triads and upper-case numerals for major triads, and degree and plus signs ( and ) to indicate diminished and augmented triads respectively. Otherwise, all

8938-415: The note is indicated with a Roman numeral (e.g., on a four-string orchestral string instrument, I indicates the highest-pitched, thinnest string and IV indicates the lowest-pitched, thickest bass string). In some orchestral parts, chamber music and solo works for string instruments, the composer tells the performer which string to use with the Roman numeral. Alternately, the composer starts the note name with

9047-515: The numerals may be upper-case and the qualities of the chords inferred from the scale degree. Chords outside the scale can be indicated by placing a flat/sharp sign before the chord—for example, the chord E ♭ major in the key of C major is represented by ♭ III. The tonic of the scale may be indicated to the left (e.g., "F ♯ :") or may be understood from a key signature or other contextual clues. Indications of inversions or added tones may be omitted if they are not relevant to

9156-409: The omnitonic order (though he didn't approve it personally) as the way of further development of tonality was a remarkable innovation to historic and theoretic concepts of the 19th century. Tonalité ancienne Fetis described as tonality of ordre unitonique (establishing one key and remaining in that key for the duration of the piece). The principal example of this "unitonic order" tonality he saw in

9265-496: The only combinations of notes that are possible are dyads, which means that all of the chord progressions must be implied through dyads, as well as with arpeggios. Chords constructed of three notes of some underlying scale are described as triads . Chords of four notes are known as tetrads , those containing five are called pentads and those using six are hexads . Sometimes the terms trichord , tetrachord , pentachord , and hexachord are used—though these more usually refer to

9374-467: The other, the mind coordinates the tones into different series, each of which corresponds to a particular class of emotions, sentiments, and ideas. Hence these series become various types of tonalities." "But one will say, 'What is the principle behind these scales, and what, if not acoustic phenomena and the laws of mathematics, has set the order of their tones?' I respond that this principle is purely metaphysical [anthropological]. We conceive this order and

9483-425: The overall behavior of chord tones and chordal extensions". Jean-Philippe Rameau 's Treatise on Harmony (1722) is the earliest effort to explain tonal harmony through a coherent system based on acoustical principles, built upon the functional unit being the triad , with inversions. The term tonalité (tonality) was first used in 1810 by Alexandre Choron in the preface Sommaire de l'histoire de la musique to

9592-447: The parallel parts of flutes, horn and celesta, being tuned as a chord, resemble the sound of an electric organ. Chords can be represented in various ways. The most common notation systems are: While scale degrees are typically represented in musical analysis or musicology articles with Arabic numerals (e.g., 1, 2, 3, ..., sometimes with a circumflex above the numeral: [REDACTED] , [REDACTED] , [REDACTED] , ...),

9701-474: The pitch classes of any scale, not generally played simultaneously. Chords that may contain more than three notes include pedal point chords, dominant seventh chords, extended chords, added tone chords, clusters , and polychords. Polychords are formed by two or more chords superimposed. Often these may be analysed as extended chords; examples include tertian , altered chord , secundal chord , quartal and quintal harmony and Tristan chord . Another example

9810-406: The pitch material; nor is it essentially connected to the kinds of pitch structures one finds in traditional diatonic music". One area of disagreement going back to the origin of the term tonality is whether tonality is natural or inherent in acoustical phenomena, whether it is inherent in the human nervous system or a psychological construct, whether it is inborn or learned, and to what degree it

9919-446: The pitch material; nor is it essentially connected to the kinds of pitch structures one finds in traditional diatonic music". This sense (like some of the others) is susceptible to ideological employment, as Schoenberg, did by relying on the idea of a progressive development in musical resources "to compress divergent fin-de-siècle compositional practices into a single historical lineage in which his own music brings one historical era to

10028-402: The principles of connection that govern them. Ottó Károlyi writes that, "Two or more notes sounded simultaneously are known as a chord," though, since instances of any given note in different octaves may be taken as the same note, it is more precise for the purposes of analysis to speak of distinct pitch classes . Furthermore, as three notes are needed to define any common chord , three

10246-418: The scale are present in the chord, so adding more notes does not add new pitch classes. Such chords may be constructed only by using notes that lie outside the diatonic seven-note scale. Other extended chords follow similar rules, so that for example maj , maj , and maj contain major seventh chords rather than dominant seventh chords, while m , m , and m contain minor seventh chords. The third and seventh of

10355-439: The seventh: the ninth , eleventh , and thirteenth chords. For example, a minor eleventh chord such as A consists of the notes A–C–E–G–B–D: The upper structure or extensions, i.e., notes beyond the seventh, are shown here in red. This chord is just a theoretical illustration of this chord. In practice, a jazz pianist or jazz guitarist would not normally play the chord all in thirds as illustrated. Jazz voicings typically use

10464-478: The sixth chord on the sixth degree, and finally, by the accord parfait and, above all, by the unprepared seventh chord (with major third) on the dominant". Among most subtle representatives of "pluritonic order" there were Mozart and Rossini; this stage he saw as the culmination and perfection of tonalité moderne . The romantic tonality of Berlioz and especially Wagner he related to "omnitonic order" with its "insatiable desire for modulation". His prophetic vision of

10573-423: The staff indicate the intervals above the bass note to play; that is, the numbers stand for the number of scale steps above the written note to play the figured notes. For example, in the figured bass below, the bass note is a C, and the numbers 4 and 6 indicate that notes a fourth and a sixth above (F and A) should be played, giving the second inversion of the F major triad . If no numbers are written beneath

10682-501: The string to use—e.g., "sul G" means "play on the G string". Figured bass or thoroughbass is a kind of musical notation used in almost all Baroque music ( c. 1600–1750), though rarely in music from later than 1750, to indicate harmonies in relation to a conventionally written bass line . Figured bass is closely associated with chord-playing basso continuo accompaniment instruments, which include harpsichord , pipe organ and lute . Added numbers, symbols, and accidentals beneath

10791-505: The term "sonority" is often used specifically to avoid any tonal implications of the word "chord" . Chords are also used for timbre effects. In organ registers, certain chords are activated by a single key so that playing a melody results in parallel voice leading. These voices, losing independence, are fused into one with a new timbre. The same effect is also used in synthesizers and orchestral arrangements; for instance, in Ravel ’s Bolero #5

10900-402: The term tonality is used to imply that tonal music is discontinuous as a form of cultural expression from modal music (before 1600) on the one hand and atonal music (after 1910) on the other. In some literature, tonality is a generic term applied to pre-modern music, referring to the eight modes of the Western church, implying that important historical continuities underlie music before and after

11009-422: The third, seventh, and then the extensions such as the ninth and thirteenth, and in some cases the eleventh. The root is often omitted from chord voicings, as the bass player will play the root. The fifth is often omitted if it is a perfect fifth. Augmented and diminished fifths are normally included in voicings. After the thirteenth, any notes added in thirds duplicate notes elsewhere in the chord; all seven notes of

11118-409: The tonality of a piece or section in common practice music and popular music . For example, for a simple folk music song in the key of C Major, almost all of the triadic chords in the song will be Major or minor chords which are stable and consonant (e.g., in the key of C Major, commonly-used chords include D minor, F Major, G Major, etc.). The most commonly used dissonant chord in a pop song context

11227-461: The tonic chord plays an important role in establishing the tonality of a piece. "Tonal music is music that is unified and dimensional . Music is unified if it is exhaustively referable to a precompositional system generated by a single constructive principle derived from a basic scale-type; it is dimensional if it can nonetheless be distinguished from that precompositional ordering". The term tonalité originated with Alexandre-Étienne Choron and

11336-469: The tonic triad. The tonic can be a different tone in the same scale, when the work is said to be in one of the modes of the scale. Simple folk music songs often start and end with the tonic note. The most common use of the term "is to designate the arrangement of musical phenomena around a referential tonic in European music from about 1600 to about 1910". Contemporary classical music from 1910 to

11445-451: The tonic, yet harmonically tonal melodies, such as that from Mozart's The Magic Flute below, are actually "strict harmonic-rhythmic pattern[s]," and include many points "from which it is impossible, that is, illogical, unless we want to destroy the innermost sense of the whole line" to return to the tonic. Consequently, he argues, melodically tonal melodies resist harmonization and only reemerge in western music after, "harmonic tonality

11554-415: The triads (three-note chords) that have these degrees as their roots are often identified by Roman numerals (e.g., I, IV, V, which in the key of C major would be the triads C major, F major, G major). In some conventions (as in this and related articles) upper-case Roman numerals indicate major triads (e.g., I, IV, V) while lower-case Roman numerals indicate minor triads (e.g., I for a major chord and i for

11663-473: Was abandoned," as in the music of Claude Debussy : "melodic tonality plus modulation is [Debussy's] modern tonality". The noun "tonality" and adjective "tonal" are widely applied also, in studies of early and modern Western music, and in non-Western traditional music ( Arabic maqam , Indian raga , Indonesian slendro etc.), to the "systematic arrangements of pitch phenomena and relations between them". Felix Wörner, Ullrich Scheideler, and Philip Rupprecht in

11772-401: Was borrowed by François-Joseph Fétis in 1840. According to Carl Dahlhaus , however, the term tonalité was only coined by Castil-Blaze in 1821. Although Fétis used it as a general term for a system of musical organization and spoke of types de tonalités rather than a single system, today the term is most often used to refer to major–minor tonality, the system of musical organization of

11881-425: Was entirely natural and, following Moritz Hauptmann , that the major third and perfect fifth were the only "directly intelligible" intervals, and that I, IV, and V, the tonic, subdominant, and dominant were related by the perfect fifths between their root notes. It is in this era that the word tonality was popularized by Fétis. Theorists such as Hugo Riemann, and later Edward Lowinsky and others, pushed back
