Herbert Jeffrey "Herbie" Hancock (born April 12, 1940) is a jazz pianist and composer. His music embraces elements of rock and soul while adopting freer stylistic elements from jazz.
As part of Miles Davis's "second great quintet", Hancock helped redefine the role of a jazz rhythm section, and was one of the primary architects of the "post-bop" sound. Later, he was one of the first jazz musicians to embrace synthesizers and funk. Yet for all his restless experimentalism, Hancock's music is often melodic and accessible; he has had many songs "cross over" and achieved success among pop audiences.
Herbie's best-known solo works include "Cantaloupe Island", "Watermelon Man" (later performed by dozens of musicians, including bandleader Mongo Santamaria), "Maiden Voyage", "Chameleon", and the singles "I Thought It Was You" and "Rockit". His 2007 tribute album, "River: The Joni Letters" won the 2008 Grammy Award for Album of the Year, only the second jazz album to win the award.
