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 ...
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.

Tritone substitutions are sometimes used in improvisation —often to create tension during a solo.
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). Thus, this upper structure can be called upper ...

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.
In jazz harmony, a So What chord is a particular 5-note chord voicing. From the bottom note upwards, it consists of three perfect fourth intervals followed by a major third interval. It was employed by Bill Evans in the "'amen' response figure " [1] to the head of the Miles Davis tune "So What". For example, an "E minor" So What chord is an Em ...
