The tritone substitution is a common chord substitution found in both jazz and classical music. Where jazz is concerned, it was the precursor to more complex substitution patterns like Coltrane changes. Tritone substitutions are sometimes used in improvisation —often to create tension during a solo.
Jazz improvisation is the spontaneous invention of melodic solo lines or accompaniment parts in a performance of jazz music. It is one of the defining elements of jazz. Improvisation is composing on the spot, when a singer or instrumentalist invents melodies and lines over a chord progression played by rhythm section instruments (piano, guitar ...
Common jazz parlance refers to upper structures by way of the interval between the root of the bottom chord and the root of the triad juxtaposed above it. [2] For instance, in example one above (C 7 ♯ 9) the triad of E ♭ major is a (compound) minor 3rd away from C (root of the bottom chord).
Altered scale. In jazz, the altered scale, altered dominant scale, or Super Locrian scale ( Locrian ♭4 scale) is a seven-note scale that is a dominant scale where all non-essential tones have been altered. This means that it comprises the three irreducibly essential tones that define a dominant seventh chord, which are root, major third, and ...
Outside (jazz) In jazz improvisation, outside playing describes approaches where one plays over a scale, mode or chord that is harmonically distant from the given chord. There are several common techniques to playing outside, that include side-stepping or side-slipping, superimposition of Coltrane changes, [1] and polytonality.
The jazz minor scale or ascending melodic minor scale is a derivative of the melodic minor scale, except only the ascending form of the scale is used. As the name implies, it is primarily used in jazz [citation needed], although it may be found in other types of music as well. It may be derived from the major scale with a minor third, [ 1 ...
Backdoor compared with the dominant (front door) in the chromatic circle: they share two tones and are transpositionally equivalent. In jazz and jazz harmony, the chord progression from iv 7 to ♭ VII 7 to I (the tonic or "home" chord) has been nicknamed the backdoor progression [1] [2] or the backdoor ii-V, as described by jazz theorist and author Jerry Coker.
The two octatonic scales on C. An octatonic scale is any eight- note musical scale. However, the term most often refers to the ancohemitonic symmetric scale composed of alternating whole and half steps, as shown at right. In classical theory (in contrast to jazz theory ), this symmetrical scale is commonly called the octatonic scale (or the ...
