Chi Chi is a bebop blues composition by Charlie Parker, created during a January 1953 recording session in New York produced by Norman Granz. The tune is a 12-bar blues in Ab major, featuring a fast, driving melody with the angular phrasing and rhythmic propulsion characteristic of Parker's style. According to drummer Max Roach, who was present at the session, Parker arrived without prepared material and composed Chi Chi on the spot, humming and notating the melody while Roach played a steady four-beat rhythm. This spontaneous method of composition was typical of Parker's later career, where he often generated new heads as immediate vehicles for recording rather than through extended compositional revision. The melody sits atop a bebop blues harmonic framework, with changes that share similarities with other Parker blues compositions such as Blues for Alice, though the specific voicings and passing chords have varied across different published lead sheets and subsequent performances. The tune's uptempo character and syncopated head make it both accessible in form and demanding in execution, requiring fluency in bebop vocabulary to navigate convincingly. Chi Chi has become a recognized part of the bebop repertoire, included in the Charlie Parker Omnibook and various jazz education materials. It is regularly performed and studied as an example of Parker's approach to the blues form, occupying a place in the standard canon alongside his more widely known compositions.
