Mulgrew Miller (August 13, 1955 – May 29, 2013) was an American jazz pianist, composer, and educator. As a child he played in churches and was influenced on piano by Ramsey Lewis and then Oscar Peterson. Aspects of their styles remained in his playing, but he added the greater harmonic freedom of McCoy Tyner and others in developing as a hard bop player and then in creating his own style, which influenced others from the 1980s on.
Miller's style evolved through playing with a series of major jazz figures. After leaving university he was pianist with the Duke Ellington Orchestra for three years, then accompanied vocalist Betty Carter. Three-year stints with trumpeter Woody Shaw and with drummer Art Blakey's high-profile Jazz Messengers followed, by the end of which Miller had formed his own bands and begun recording under his own name. He was then part of drummer Tony Williams' quintet from its foundation, while continuing to play and record with numerous other leaders, mostly in small groups. Miller was Director of Jazz Studies at William Paterson University from 2005, and continued to play and tour internationally with other high-profile figures in the music until his death from a stroke at the age of 57.
