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" and Parker's "Confirmation" also have similar progressions.
