"Blues for Alice" is a composition by Charlie Parker that reimagines the twelve-bar blues through a series of descending ii-V chord progressions, creating a much denser and more sophisticated harmonic path than a traditional blues. First recorded on August 8, 1951 for Verve Records with Red Rodney on trumpet, John Lewis on piano, Ray Brown on bass, and Kenny Clarke on drums, it introduced what became known as "Bird Changes" or "Bird Blues" — a reharmonization approach that fundamentally changed how jazz musicians think about the blues form. Rather than moving directly between the basic chords of a blues, Parker's progression fills the space with secondary dominants and chromatic voice leading, requiring improvisers to navigate rapid harmonic movement while keeping the underlying blues structure intact. The composition has been recorded over twenty-five times by artists including Sonny Stitt, Mark Whitfield, and Anthony Braxton, and it serves as a cornerstone of jazz education for teaching bebop harmony. Its chord changes also became a template for other composers — Tommy Flanagan's "Freight Trane" and Toots Thielemans's "Bluesette" both draw on the Bird Blues progression that Parker established here. Despite being one of the most harmonically complex blues in the standard repertoire, the melody itself remains accessible and singable, balancing Parker's sophistication with the directness of the blues tradition.
