Pitch is a perceptual property that allows sounds to be ordered on a frequency -related scale , or more commonly, pitch is the quality that makes it possible to judge sounds as "higher" and "lower" in the sense associated with musical melodies . Pitch is a major auditory attribute of musical tones , along with duration , loudness , and timbre .
96-399: Tonality 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
192-431: 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
288-477: 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

Below 500 Hz, the jnd is about 3 Hz for sine waves, and 1 Hz for complex tones; above 1000 Hz, the jnd for sine waves is about 0.6% (about 10 cents ). The jnd is typically tested by playing two tones in quick succession with the listener asked if there was a difference in their pitches. The jnd becomes smaller if
480-618: 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
576-429: 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
672-461: 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
768-400: A hierarchy among the notes of the chromatic scale so that they are all referentially related to one or two pitches which then function as a tonic note or chord in tonality . The system similarly creates a hierarchy among intervals and finally, among larger collections of notes, 'chords.' The main debt of this system to the 12-tone system lies in its use of an ordered linear succession in
864-422: 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
960-443: A non-transposing instrument like a violin calls B ♭ ." Pitches are labeled using: For example, one might refer to the A above middle C as a′ , A 4 , or 440 Hz . In standard Western equal temperament , the notion of pitch is insensitive to "spelling": the description "G 4 double sharp" refers to the same pitch as A 4 ; in other temperaments, these may be distinct pitches. Human perception of musical intervals

This creates a linear pitch space in which octaves have size 12, semitones (the distance between adjacent keys on the piano keyboard) have size 1, and A440 is assigned the number 69.

These properties are represented by a unique set of rules dictating the unfolding of harmonic function, voice-leading conventions, and

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,

The precise way this temporal structure helps code for pitch at higher levels is still debated, but the processing seems to be based on an autocorrelation of action potentials in the auditory nerve. However, it has long been noted that a neural mechanism that may accomplish a delay—a necessary operation of a true autocorrelation—has not been found. At least one model shows that a temporal delay

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.

Dominant function requires a major-quality triad with a root a perfect fifth above
2208-449: Is a subjective psychoacoustical attribute of sound. Historically, the study of pitch and pitch perception has been a central problem in psychoacoustics, and has been instrumental in forming and testing theories of sound representation, processing, and perception in the auditory system. Pitch is an auditory sensation in which a listener assigns musical tones to relative positions on a musical scale based primarily on their perception of
2304-468: 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
2400-538: Is almost entirely determined by how quickly the sound wave is making the air vibrate and has almost nothing to do with the intensity, or amplitude , of the wave. That is, "high" pitch means very rapid oscillation, and "low" pitch corresponds to slower oscillation. Despite that, the idiom relating vertical height to sound pitch is shared by most languages. At least in English, it is just one of many deep conceptual metaphors that involve up/down. The exact etymological history of

Motivated by this logarithmic perception, music theorists sometimes represent pitches using a numerical scale based on the logarithm of fundamental frequency. For example, one can adopt the widely used MIDI standard to map fundamental frequency, f , to

A sound generated on any instrument produces many modes of vibration that occur simultaneously. A listener hears numerous frequencies at once. The vibration with the lowest frequency is called the fundamental frequency ; the other frequencies are overtones . Harmonics are an important class of overtones with frequencies that are integer multiples of

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
2880-494: Is still possible for two sounds of indefinite pitch to clearly be higher or lower than one another. For instance, a snare drum sounds higher pitched than a bass drum though both have indefinite pitch, because its sound contains higher frequencies. In other words, it is possible and often easy to roughly discern the relative pitches of two sounds of indefinite pitch, but sounds of indefinite pitch do not neatly correspond to any specific pitch. A pitch standard (also concert pitch )

In pop music, the listener will expect this tritone to be resolved to a consonant, stable chord (in this case, typically

Concert pitch may vary from ensemble to ensemble, and has varied widely over musical history. Standard pitch is a more widely accepted convention. The A above middle C is usually set at 440 Hz (often written as "A = 440 Hz " or sometimes "A440"), although other frequencies, such as 442 Hz, are also often used as variants. Another standard pitch,

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".

This technique was different from, but related to, the twelve-tone technique of the Second Viennese School , of which he was an "early admirer" and whose techniques he used aspects of but never fully adopted. Perle's former student Paul Lansky described Perle's twelve-tone tonality thus: Basically this creates
3552-438: The constant-Q transform is used, displaying the musical signal on a log frequency scale. Although a radical (over)simplification of the concept of tonality, such methods can predict the key of classical Western music well for most pieces. Other methods also take into consideration the sequentiality of music. Pitch (music) Pitch may be quantified as a frequency , but pitch is not a purely objective physical property; it
3648-620: The frequency of vibration ( audio frequency ). Pitch is closely related to frequency, but the two are not equivalent. Frequency is an objective, scientific attribute which can be measured. Pitch is the subjective perception of a sound wave by the individual person, which cannot be directly measured. However, this does not necessarily mean that people will not agree on which notes are higher and lower. The oscillations of sound waves can often be characterized in terms of frequency . Pitches are usually associated with, and thus quantified as, frequencies (in cycles per second, or hertz), by comparing

3840-538: The octave doubles the frequency of a note; for example, an octave above A440 is 880 Hz. If however the first overtone is sharp due to inharmonicity , as in the extremes of the piano, tuners resort to octave stretching . In atonal , twelve tone , or musical set theory , a "pitch" is a specific frequency while a pitch class is all the octaves of a frequency. In many analytic discussions of atonal and post-tonal music, pitches are named with integers because of octave and enharmonic equivalency (for example, in

As a result, musicians need a way to refer to a particular pitch in an unambiguous manner when talking to each other. For example,

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.

When averaged, the remaining shifts followed the directions of Stevens's curves but were small (2% or less by frequency, i.e. not more than a semitone). Theories of pitch perception try to explain how the physical sound and specific physiology of the auditory system work together to yield the experience of pitch. In general, pitch perception theories can be divided into place coding and temporal coding . Place theory holds that

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

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
5376-427: 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
5472-455: 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
5568-555: 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.

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 ",

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

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

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
7008-466: 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
7104-456: The output of the cochlea , as via auditory-nerve interspike-interval histograms. Some theories of pitch perception hold that pitch has inherent octave ambiguities, and therefore is best decomposed into a pitch chroma , a periodic value around the octave, like the note names in Western music—and a pitch height , which may be ambiguous, that indicates the octave the pitch is in. The just-noticeable difference (jnd) (the threshold at which
7200-422: 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
7296-420: The perception of pitch is determined by the place of maximum excitation on the basilar membrane . A place code, taking advantage of the tonotopy in the auditory system, must be in effect for the perception of high frequencies, since neurons have an upper limit on how fast they can phase-lock their action potentials . However, a purely place-based theory cannot account for the accuracy of pitch perception in
7392-408: The physical frequencies of the pure tones, and the combination tone at 200 Hz, corresponding to the repetition rate of the waveform. In a situation like this, the percept at 200 Hz is commonly referred to as the missing fundamental , which is often the greatest common divisor of the frequencies present. Pitch depends to a lesser degree on the sound pressure level (loudness, volume) of
7488-405: 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
7584-445: 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
7680-474: The root of 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
7776-524: The same way that a 12-tone set does". In 1968, Perle cofounded the Alban Berg Society with Igor Stravinsky , and Hans F. Redlich , who had the idea (according to Perle in his letter to Glen Flax of 4/1/89 ). Perle's important work on Berg includes documenting that the third act of Lulu , rather than being an unfinished sketch, was actually three-fifths complete and that the Lyric Suite contains
7872-476: 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
7968-404: The so-called Baroque pitch , has been set in the 20th century as A = 415 Hz—approximately an equal-tempered semitone lower than A440 to facilitate transposition. The Classical pitch can be set to either 427 Hz (about halfway between A415 and A440) or 430 Hz (also between A415 and A440 but slightly sharper than the quarter tone). And ensembles specializing in authentic performance set
8064-490: The sounds being assessed against sounds with pure tones (ones with periodic , sinusoidal waveforms). Complex and aperiodic sound waves can often be assigned a pitch by this method. According to the American National Standards Institute , pitch is the auditory attribute of sound allowing those sounds to be ordered on a scale from low to high. Since pitch is such a close proxy for frequency, it
8160-402: 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
8256-409: 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
8352-489: The tone, especially at frequencies below 1,000 Hz and above 2,000 Hz. The pitch of lower tones gets lower as sound pressure increases. For instance, a tone of 200 Hz that is very loud seems one semitone lower in pitch than if it is just barely audible. Above 2,000 Hz, the pitch gets higher as the sound gets louder. These results were obtained in the pioneering works by S. Stevens and W. Snow. Later investigations, e.g. by A. Cohen, have shown that in most cases
8448-459: 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
8544-450: 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
8640-399: The two tones are played simultaneously as the listener is then able to discern beat frequencies . The total number of perceptible pitch steps in the human hearing range is about 1,400; the total number of notes in the equal-tempered scale, from 16 to 16,000 Hz, is 120. The relative perception of pitch can be fooled, resulting in aural illusions . There are several of these, such as
8736-475: The west, the twelve-note chromatic scale is the most common method of organization, with equal temperament now the most widely used method of tuning that scale. In it, the pitch ratio between any two successive notes of the scale is exactly the twelfth root of two (or about 1.05946). In well-tempered systems (as used in the time of Johann Sebastian Bach , for example), different methods of musical tuning were used. In almost all of these systems interval of
8832-471: 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
8928-594: Was also around this time that he had published his fourth book entitled The Listening Composer . He died aged 93 in his home in New York City in January 2009. He was buried in Calverton National Cemetery . A growing number of younger artists have come to express their appreciation for Perle. In the run-up to his 100th birthday celebrations the composer-pianist Michael Brown released a well received CD of
9024-452: Was an American composer and music theorist . As a composer, his music was largely atonal , using methods similar to the twelve-tone technique of the Second Viennese School . This serialist style, and atonality in general, was the subject of much of his theoretical writings. His 1962 book, Serial Composition and Atonality: An Introduction to the Music of Schoenberg, Berg, and Webern remains
9120-399: 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
9216-421: 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
