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. [2]
The ii–V–I progression ("two–five–one progression") (occasionally referred to as ii–V–I turnaround, and ii–V–I) is a common cadential chord progression used in a wide variety of music genres, including jazz harmony. It is a succession of chords whose roots descend in fifths from the second degree ( supertonic) to the fifth ...
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.
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.

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).
The Blues for Alice changes, Bird changes, Bird Blues, or New York Blues changes, is a chord progression, often named after Charlie Parker ("Bird"), which is a variation of the twelve-bar blues . The progression uses a series of sequential ii–V or secondary ii–V progressions, and has been used in pieces such as Parker's "Blues for Alice".
