Barry Doyle Harris was an American jazz pianist, bandleader, composer, arranger, and educator. He was an exponent of the bebop style. Influenced by Thelonious Monk and Bud Powell, Harris in turn influenced and mentored bebop musicians including Donald Byrd, Paul Chambers, Curtis Fuller, Joe Henderson, Charles McPherson, and Michael Weiss.

Bebop or bop is a style of jazz developed in the early to mid-1940s in the United States. The style features compositions characterized by a fast tempo, complex chord progressions with rapid chord changes and numerous changes of key, instrumental virtuosity, and improvisation based on a combination of harmonic structure, the use of scales and occasional references to the melody.
