What instrument did jazz great Thelonious Monk play?

Thelonious Monk played the piano. The instrument was central to his identity as one of jazz’s most distinctive pianists and composers.

Monk began studying piano as a child after briefly trying the trumpet. He learned stride piano from neighborhood teacher Alberta Simmons, absorbing the influence of players such as James P. Johnson, Fats Waller, and Eubie Blake. His early work at Minton’s Playhouse in Harlem helped shape the emerging bebop movement during the 1940s.

Monk’s piano style was unusually percussive, angular, and spacious. He used unexpected silences, dissonant intervals, chromatic notes, and sharply accented chords. His compositions, including “’Round Midnight,” “Straight, No Chaser,” and “Blue Monk,” became jazz standards.

A common mix-up is assuming Monk was primarily a bandleader who played multiple instruments. Although he briefly studied trumpet and sometimes worked as an organist, the piano was his defining instrument. His unusual posture, hats, and habit of briefly dancing beside the piano also became part of his legend.
