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] and Parker's "Confirmation"[2] also have similar progressions.
