Thelonious Sphere Monk (Rocky Mount, North Carolina 10th October 1917 - Hartsdale, New York 17th February 1982) was a jazz pianist and composer. Widely considered as one of the most important musicians in jazz -- he is one of only five jazz musicians to be featured on the cover of Time -- Monk had a unique improvisational style and made numerous contributions to the standard jazz repertoire, including "Epistrophy," "'Round Midnight," "Blue Monk," "Straight No Chaser" and "Well, You Needn't."
