Composed by Clifford Brown for the February 25, 1955 session that produced the Study in Brown album, Swingin' is an uptempo contrafact built on the chord changes of I Never Knew (I Could Love Anybody Like I'm Loving You), a popular standard from the 1920s. Written in the key of A-flat, the tune was conceived as the kind of hard-driving opener the quintet would use to ignite a set on club dates, and at just under three minutes in its original recorded form, it wastes no time making its case. The melody is blues-inflected and rhythmically insistent, propelled at what contemporaries described as breakneck speed, with the ensemble locked into the precise, swinging interplay that defined the Brown-Roach partnership. Though it has not entered the widely covered standard repertoire in the way that Joy Spring or Daahoud have, Swingin' has attracted attention from other notable players. Saxophonist Tina Brooks recorded a version at the Five Spot Cafe with Art Blakey on drums, taken at a more relaxed tempo and featuring a restructured intro and coda that emphasized a backbeat feel on beats two and four. That performance remained unissued until a 1986 CD reissue brought it to light. Brown's original trumpet solo has been a subject of transcription and pedagogical analysis, valued for its melodic logic and rhythmic inventiveness within hard bop vocabulary. The tune endures as a deep cut that rewards close listening, a characteristic specimen of the quintet's working repertoire beyond its most famous compositions.
