"Mozzin'" is a composition by John Farnsworth, a jazz musician known as both a drummer and composer. The tune was written for inclusion on pianist Harold Mabern's 2015 album Afro Blue on Smoke Sessions Records, where it was recorded by the Harold Mabern Trio with Joe Farnsworth on drums and John Webber on bass. The piece is a soulful, hard-swinging instrumental that evokes the aesthetic of 1960s Blue Note Records, grounded in blues-rooted phrasing and straight-ahead swing. Its character draws from the tradition of small-group hard bop and soul jazz, featuring an energetic rhythmic foundation that allows for sustained improvisational exploration. On the Afro Blue album, the tune appears as one of three instrumental tracks closing the program, placed alongside two other non-standard selections that showcase Mabern's ability to inhabit varied compositional voices. Mabern's performance highlights his characteristic left-hand activity and percussive single-note lines, bringing his trademark intensity to Farnsworth's composition. Beyond the original studio recording, the tune has been performed live by the John Farnsworth Sextet, but it has not entered wide circulation in the jazz repertoire. "Mozzin'" remains a specialized composition appreciated primarily within the orbit of its composer and the musicians who first brought it to life on record.
