Sonny Criss
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.
Alto saxophonist Charlie Parker was a leading performer and composer of the bebop era. He is pictured here with Tommy Potter, Max Roach and Miles Davis at the Three Deuces club in New York City.
