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 ...
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). Thus, this upper structure can be called upper structure flat three, or US ♭ III for short. Other possible upper structures are: USII – e.g. D major over C 7, resulting in C 13 ♯ 11
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.
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 ...
See media help. In the standard Coltrane change cycle the ii–V–I is substituted with a progression of chords that cycle back to the V–I at the end. In a 44 piece, each chord gets two beats per change. Coltrane developed this modified chord progression for "Countdown", which is much more complex.
For instance, in C major, a jazz musician may alter the V chord, G 7 (G–B–D–F), with a flattened fifth, producing the chord G 7 ♭ 5 (G–B–D ♭ –F). An improviser might then choose a scale containing these four notes, such as the G whole tone scale, the G octatonic scale, or a mode of either D or A ♭ melodic minor ascending.
Improvisation Advisor. The philosophy of Impro-Visor is to provide a tool to help musicians construct jazz solos over chord progressions. It includes a database capability for creating, saving, and recalling licks, as well as a lick generation capability based on a user-modifiable grammar.
