Bird changes

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". Toots Thielemans's "Bluesette",[1] Freight Trane written by pianist Tommy Flanagan, and Parker's "Confirmation"[2] also have similar progressions.

The Bird Blues progression, in C, is as follows:[4]

In roman numeral analysis, this is represented by

IM7 viiø7   III7 vi7    II7 v7     I7
IV7 iv7    ♭VII7 iii7    VI7 ♭iii7  ♭VI7
ii7 V7 IM7   VI7 ii7     V7

This can be viewed as a cycle of ii–V progressions leading to the IV chord (F7 in the key of C major), and the tritone substitution of the dominant chords leading by half-step to the V chord (G7 in C).[4]

C: Am: G(m): F:

F: E♭: D: D♭(m):
