Roland Hanna Day
Roland Pembroke Hanna (February 10, 1932 – November 13, 2002) was an American jazz pianist, composer, and teacher.
Hanna studied classical piano from the age of 11, but was strongly interested in jazz, having been introduced to it by his friend, pianist Tommy Flanagan. This interest increased after his time in military service, 1950–52. He studied briefly at the Eastman School of Music in 1953 and then enrolled at the Juilliard School when he moved to New York two years later. He worked with several big names in the 1950s, including Benny Goodman and Charles Mingus, and graduated in 1960. Between 1963 and 1966 Hanna led his own trio, then from 1966 to 1974 he was a regular member of the Thad Jones/Mel Lewis Orchestra. Hanna also toured the Soviet Union with this orchestra in 1972. During the 1970s he was a member of the New York Jazz Quartet.
