Jazz Scale
A jazz scale is any musical scale used in jazz. Many "jazz scales" are common scales drawn from Western European classical music, including the diatonic, whole-tone, octatonic (or diminished), and the modes of the ascending melodic minor. All of these scales were commonly used by late nineteenth and early twentieth-century composers such as Rimsky-Korsakov, Debussy, Ravel and Stravinsky, often in ways that directly anticipate jazz practice. Some jazz scales, such as the bebop scales, add additional chromatic passing tones to the familiar diatonic scales. Theory One important feature of jazz is what theorists call "the principles of chord-scale compatibility": the idea that a sequence of chords will generate a sequence of compatible scales. In classical major-mode harmony, chords typically belong to the same scale. For example, a ii–V–I progression in C major will typically use only the notes of the C diatonic collection. In jazz, a four-chord progression may use four di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chord-scale System
The chord-scale system is a method of matching, from a list of possible chords, a list of possible scales.Mervyn Cooke, David Horn (2003). '' The Cambridge companion to jazz'', p.266. . The system has been widely used since the 1970s and is "generally accepted in the jazz world today". However, the majority of older players used the chord tone/chord arpeggio method. The system is an example of the difference between the treatment of dissonance in jazz and classical harmony: "Classical treats all notes that don't belong to the chord...as potential dissonances to be resolved...Non-classical harmony just tells you which note in the scale to otentially avoid..., meaning that all the others are okay". The chord-scale system may be compared with other common methods of improvisation, first, the older traditional chord tone/chord arpeggio method, and where one scale on one root note is used throughout all chords in a progression (for example the blues scale on A for all chords of t ...

Altered Chord
An altered chord is a chord that replaces one or more notes from the diatonic scale with a neighboring pitch from the chromatic scale. By the broadest definition, any chord with a non-diatonic chord tone is an altered chord. The simplest example of altered chords is the use of borrowed chords, chords borrowed from the parallel key, and the most common is the use of secondary dominants. As Alfred Blatter explains, "An altered chord occurs when one of the standard, functional chords is given another quality by the modification of one or more components of the chord." For example, altered notes may be used as leading tones to emphasize their diatonic neighbors. Contrast this with chord extensions: In jazz harmony, chromatic alteration is either the addition of notes not in the scale or expansion of a hordprogression by adding extra non-diatonic chords.Arkin, Eddie (2004). ''Creative Chord Substitution for Jazz Guitar'', p. 42. . For example, "A C major scale with an added D ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heptatonic Scale
A heptatonic scale is a musical scale that has seven pitches, or tones, per octave. Examples include the major scale or minor scale; e.g., in C major: C D E F G A B C—and in the relative minor, A minor, natural minor: A B C D E F G A; the melodic minor scale, A B C D E FGA ascending, A G F E D C B A descending; the harmonic minor scale, A B C D E F GA; and a scale variously known as the Byzantine, and Hungarian,''The New Grove Dictionary of Music and Musicians'', second edition, edited by Stanley Sadie and John Tyrrell (London, 2001) scale, C D E F G A B C. Indian classical theory postulates seventy-two seven-tone scale types, collectively called ''thaat'', whereas others postulate twelve or ten (depending on the theorist) seven-tone scale types. Several heptatonic scales in Western, Roman, Spanish, Hungarian, and Greek music can be analyzed as juxtapositions of tetrachords.Dupré, Marcel (1962).

Chromatic Passing Tone
A nonchord tone (NCT), nonharmonic tone, or embellishing tone is a note in a piece of music or song that is not part of the implied or expressed chord set out by the harmonic framework. In contrast, a chord tone is a note that is a part of the functional chord (see: factor (chord)). Non-chord tones are most often discussed in the context of the common practice period of classical music, but they can be used in the analysis of other types of tonal music as well, such as Western popular music. Nonchord tones are often categorized as ''accented non-chord tones'' and ''unaccented non-chord tones'' depending on whether the dissonance occurs on an accented or unaccented beat (or part of a beat). Over time, some musical styles assimilated chord types outside of the common-practice style. In these chords, tones that might normally be considered nonchord tones are viewed as chord tones, such as the seventh of a minor seventh chord. For example, in 1940s-era bebop jazz, an F played with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Locrian Mode
The Locrian mode is the seventh mode of the major scale. It is either a musical mode or simply a diatonic scale. On the piano, it is the scale that starts with B and only uses the white keys from there. Its ascending form consists of the key note, then: half step, whole step, whole step, half step, whole step, whole step, whole step. :: History ''Locrian'' is the word used to describe the inhabitants of the ancient Greek regions of Locris. Although the term occurs in several classical authors on music theory, including Cleonides (as an octave species) and Athenaeus (as an obsolete ''harmonia''), there is no warrant for the modern usage of Locrian as equivalent to Glarean's Hyperaeolian mode, in either classical, Renaissance, or later phases of modal theory through the 18th century, or modern scholarship on ancient Greek musical theory and practice. The name first came to be applied to modal chant theory after the 18th century, when it was used to describe the mode newly-numbe ...

Aeolian Mode
The Aeolian mode is a musical mode or, in modern usage, a diatonic scale also called the natural minor scale. On the white piano keys, it is the scale that starts with A. Its ascending interval form consists of a ''key note, whole step, half step, whole step, whole step, half step, whole step, whole step.'' That means that, in A aeolian (or A minor), you would play A, move up a whole step (two piano keys) to B, move up a half step (one piano key) to C, then up a whole step to D, a whole step to E, a half step to F, a whole step to G, and a final whole step to a high A. : History The word ''Aeolian'', like the names for the other ancient Greek ''tonoi'' and ''harmoniai'', is an ethnic designation: in this case, for the inhabitants of Aeolis (Αἰολίς)—the Aeolian Islands and adjacent coastal district of Asia Minor. In the music theory of ancient Greece, it was an alternative name (used by some later writers, such as Cleonides) for what Aristoxenus called the Low Lydian '' ...

Mixolydian Mode
Mixolydian mode may refer to one of three things: the name applied to one of the ancient Greek ''harmoniai'' or ''tonoi'', based on a particular octave species or scale; one of the medieval church modes; or a modern musical mode or diatonic scale, related to the medieval mode. (The Hypomixolydian mode of medieval music, by contrast, has no modern counterpart.) The modern diatonic mode is the scale forming the basis of both the rising and falling forms of Harikambhoji in Carnatic music, the classical music form of southern India. Greek Mixolydian The idea of a Mixolydian mode comes from the music theory of ancient Greece. The invention of the ancient Greek Mixolydian mode was attributed to Sappho, the poet and musician. However, what the ancient Greeks thought of as Mixolydian is very different from the modern interpretation of the mode. The prefix ''mixo''- (μιξο-) means "half", referring to its resemblance to the Lydian mode. In Greek theory, the Mixolydian ''tonos'' ...

Lydian Mode
The modern Lydian mode is a seven-tone musical scale formed from a rising pattern of pitches comprising three whole tones, a semitone, two more whole tones, and a final semitone. : Because of the importance of the major scale in modern music, the Lydian mode is often described as the scale that begins on the fourth scale degree of the major scale, or alternatively, as the major scale with the fourth scale degree raised half a step. This sequence of pitches roughly describes the scale underlying the fifth of the eight Gregorian (church) modes, known as Mode V or the authentic mode on F, theoretically using B but in practice more commonly featuring B. The use of the B as opposed to B would have made such piece in the modern day F major scale. Ancient Greek Lydian The name Lydian refers to the ancient kingdom of Lydia in Anatolia. In Greek music theory, there was a Lydian scale or "octave species" extending from ''parhypate hypaton'' to ''trite diezeugmenon'', equivalent in th ...

Phrygian Mode
The Phrygian mode (pronounced ) can refer to three different musical modes: the ancient Greek ''tonos'' or ''harmonia,'' sometimes called Phrygian, formed on a particular set of octave species or scales; the Medieval Phrygian mode, and the modern conception of the Phrygian mode as a diatonic scale, based on the latter. Ancient Greek Phrygian The octave species (scale) underlying the ancient-Greek Phrygian ''tonos'' (in its diatonic genus) corresponds to the medieval and modern Dorian mode. The terminology is based on the '' Elements'' by Aristoxenos (fl. c. 335 BC), a disciple of Aristotle. The Phrygian ''tonos'' or ''harmonia'' is named after the ancient kingdom of Phrygia in Anatolia. In Greek music theory, the ''harmonia'' given this name was based on a ''tonos'', in turn based on a scale or octave species built from a tetrachord which, in its diatonic genus, consisted of a series of rising intervals of a whole tone, followed by a semitone, followed by a whole tone. : In ...

Dorian Mode
Dorian mode or Doric mode can refer to three very different but interrelated subjects: one of the Ancient Greek ''harmoniai'' (characteristic melodic behaviour, or the scale structure associated with it); one of the medieval musical modes; or—most commonly—one of the modern modal diatonic scales, corresponding to the piano keyboard's white notes from D to D, or any transposition of itself. : Greek Dorian mode The Dorian mode (properly ''harmonia'' or ''tonos'') is named after the Dorian Greeks. Applied to a whole octave, the Dorian octave species was built upon two tetrachords (four-note segments) separated by a whole tone, running from the ''hypate meson'' to the ''nete diezeugmenon''. In the enharmonic genus, the intervals in each tetrachord are quarter tone–quarter tone–major third. : In the chromatic genus, they are semitone–semitone–minor third. : In the diatonic genus, they are semitone–tone–tone. : In the diatonic genus, the sequence over the ...

Ionian Mode
Ionian mode is a musical mode or, in modern usage, a diatonic scale also called the major scale. It is the name assigned by Heinrich Glarean in 1547 to his new authentic mode on C (mode 11 in his numbering scheme), which uses the diatonic octave species from C to the C an octave higher, divided at G (as its dominant, reciting tone/reciting note or ''tenor'') into a fourth species of perfect fifth (tone–tone–semitone–tone) plus a third species of perfect fourth (tone–tone–semitone): C D E F G + G A B C. This octave species is essentially the same as the major mode of tonal music. Church music had been explained by theorists as being organised in eight musical modes: the scales on D, E, F, and G in the "greater perfect system" of "musica recta," each with their authentic and plagal counterparts. Glarean's twelfth mode was the plagal version of the Ionian mode, called Hypoionian (under Ionian), based on the same relative scale, but with the major third as its ''tenor' ...

Major Scale
The major scale (or Ionian mode) is one of the most commonly used musical scales, especially in Western music. It is one of the diatonic scales. Like many musical scales, it is made up of seven notes: the eighth duplicates the first at double its frequency so that it is called a higher octave of the same note (from Latin "octavus", the eighth). The simplest major scale to write is C major, the only major scale not requiring sharps or flats: The major scale had a central importance in Western music, particularly in the common practice period and in popular music. In Carnatic music, it is known as '' Sankarabharanam''. In Hindustani classical music, it is known as '' Bilaval''. Structure A major scale is a diatonic scale. The sequence of intervals between the notes of a major scale is: : whole, whole, half, whole, whole, whole, half where "whole" stands for a whole tone (a red u-shaped curve in the figure), and "half" stands for a semitone (a red angled line in the figu ...
