Earl Rudolph "Bud" Powell (September 27, 1924 – July 31, 1966) was an American jazz pianist and composer. A pioneer in the development of bebop and its associated contributions to jazz theory, Powell's application of complex phrasing to the piano influenced both his contemporaries and later pianists including Walter Davis Jr., Toshiko Akiyoshi, and Barry Harris.
Born in the midst of the Harlem Renaissance to a musical family, Powell, during the 1930s, developed an attacking, right-handed approach to the piano, which marked a break from the left-handed approach of stride and ragtime that had been prevalent.
