Billie's Bounce was composed by Charlie Parker and first recorded on November 26, 1945, at WOR Studios in New York City for Savoy Records, as part of Parker's debut session as a leader. The title was intended as Bill's Bounce, a dedication to Parker's booking agent Billy Shaw, but a label error changed the spelling and the altered name stuck. The session featured Miles Davis on trumpet, Dizzy Gillespie on piano, Curly Russell on bass, and Max Roach on drums. Take 5 was issued as the master, though the multiple alternate takes have become essential listening for studying Parker's improvisational brilliance. The composition applies a sophisticated, syncopated bebop melody over a twelve-bar blues structure, incorporating characteristic harmonic devices such as early IV chord entries, diminished passing chords, and temporary II-V-I progressions that create momentary key center shifts before resolving back to the tonic. As one of the most important blues heads in jazz, it became a cornerstone of the bebop repertoire and is among the most frequently performed and recorded compositions in the idiom. On AllSolos, the tune is represented by Parker's original 1945 Savoy recording as well as sessions featuring Melissa Aldana with Emmet Cohen and a Harold Mabern date with Eric Alexander, Kurt Elling, and Jeremy Pelt. Billie's Bounce remains an essential piece for any jazz instrumentalist learning the language of bebop.
