Herbie Hancock is an American pianist, keyboardist, bandleader and composer. As part of Miles Davis's Second Great Quintet, Hancock helped to redefine the role of a jazz rhythm section and was one of the primary architects of the post-bop sound. He was one of the first jazz musicians to embrace synthesizers and funk music. In his jazz improvisation, he possesses a unique creative blend of jazz, blues, and modern classical music, with harmonic stylings much like the styles of of Claude Debussy and Maurice Ravel..
