Milt's Tune is a contrafact composed by vibraphonist Milt Jackson, built on the chord changes of I Got Rhythm, the George and Ira Gershwin standard whose harmonic framework has generated dozens of bebop compositions. Jackson, known by his nickname "Bags," was a pioneering figure in bringing the vibraphone into the bebop idiom, and his original compositions frequently served as effective vehicles for improvisation. Frank Morgan's 1955 recording for the album Gene Norman Presents Frank Morgan on GNP Crescendo provides the primary documented version of Milt's Tune, featuring a West Coast bebop septet with Morgan on alto saxophone, trumpeter Conte Candoli, tenor saxophonist Wardell Gray, guitarist Howard Roberts, pianist Carl Perkins, bassist Leroy Vinnegar, and drummer Larance Marable. The performance treats the rhythm changes framework as an open-ended blowing vehicle, with solo exchanges among five improvisers reflecting the competitive, jam-session spirit of mid-1950s bebop. The session is historically significant for capturing Wardell Gray in one of his final recordings and Morgan at the outset of a career that would be interrupted by decades of personal adversity before his celebrated 1980s comeback. Milt's Tune remains a rarely performed piece, overshadowed in Jackson's catalog by better-known originals like Bags' Groove, and is primarily associated with Morgan's debut album.
