Chromazone is an original composition by guitarist Mike Stern, first released on his 1988 album Time in Place. Written in Bb minor at a moderate tempo around 120 beats per minute, the tune is built on a distinctive repeating seven-bar chord progression centered on Em7, Gm7, and Bbm7 that gives it a propulsive, groove-oriented character. The melody is constructed from syncopated eighth-note figures traded between electric guitar and saxophone, creating a driving, funky feel that epitomizes the energy of 1980s jazz fusion. Stern's writing here balances compositional structure with open space for improvisation, making the tune an effective vehicle for extended soloing over its cyclical modal changes. The piece has become one of Stern's most recognized compositions, achieving a level of popularity in fusion circles that few of his other tunes have matched. Beyond its life as a small-group piece, Chromazone has been adapted for big band by arranger Timothy Clarke and has been covered by various instrumentalists, reflecting its durability as a composition. It serves as a staple for both tenor saxophonists and guitarists drawn to the fusion idiom, and its infectious groove and memorable head have made it a touchstone of the genre. The tune captures the essence of Stern's post-Miles Davis compositional voice, where jazz complexity meets rock energy and rhythmic immediacy.
