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"〔Hatfield, Ken (2005).
