Steeplechase is a bebop composition by Charlie Parker, built as a contrafact on the chord changes of George Gershwin's I Got Rhythm. First recorded on September 24, 1948, during a session featuring Parker on alto saxophone with Miles Davis on trumpet, John Lewis on piano, Curley Russell on bass, and Max Roach on drums, the tune exemplifies Parker's mastery of the rhythm changes form. The melody is lively and angular, driven by syncopated rhythms and dense melodic content that propels forward over the familiar harmonic framework. The A sections cycle through ii-V-I progressions in Bb major, while the bridge shifts to a sequence of dominant seventh chords that provides momentum and space for chromatic, linear improvisation. Like many of Parker's bebop heads, Steeplechase is designed as a vehicle for improvisation, with the written melody establishing a buoyant, energetic character before giving way to extended solo passages. The composition occupies a recognized place in the bebop canon, widely transcribed and taught as part of jazz education curricula. It appears in the Charlie Parker Omnibook and in collections such as Charlie Parker 60 Melodies and Solos. Guitarist John Scofield recorded a notable interpretation featuring loose phrasing and harmonic substitutions over the changes, and the tune has inspired experimental reinterpretations by artists such as Joe Diebes, demonstrating its continued relevance across stylistic boundaries.
