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" and Toots Thielemans's "Bluesette".[1] Also Parker's "Confirmation".[2]

Structure

The blues progression, in C, is as follows:

| C         | C            | C           | C           |
| F         | F            | C           | C           |
| G         | F            | C           | C           ||

The jazz blues, in C, is as follows:[3]

| C7        | F7           | C7          | C7          |
| F7        | F7           | C7          | Em7   A7    |
| Dm7       | G7           | C7    A7    | C7    G7    ||

This can be viewed as a cycle of ii-V progressions leading to the IV chord (E7 in the key of Bbmajor), and the tritone substitution of the dominant chords leading by half-step to the V chord (F7 again in Bb).[4]
