Harold Galper (born April 18, 1938) is a jazz pianist, composer, arranger, bandleader, educator, and writer.
He studied classical piano as a boy, but switched to jazz which he studied at the Berklee College of Music from 1955 to 1958. He hung out at Herb Pomeroy’s club, the Stable, hearing local Boston musicians such as Jaki Byard, Alan Dawson and Sam Rivers. Galper started sitting in and became the house pianist at the Stable and later on, at Connelly’s and Lenny’s on the Turnpike. He went on to work in Pomeroy’s band.
Between 1973-1975, Galper played in the Cannonball Adderley Quintet replacing George Duke. He performed in New York and Chicago jazz clubs in the late 1970s. Around this time, Galper recorded several times with guitarist John Scofield for the Enja label.
