John Birks "Dizzy" Gillespie was an American jazz trumpeter, bandleader, composer, educator and singer. He was a trumpet virtuoso and improviser, building on the virtuoso style of Roy Eldridge but adding layers of harmonic and rhythmic complexity previously unheard in jazz. His combination of musicianship, showmanship, and wit made him a leading popularizer of the new music called bebop. His beret and horn-rimmed spectacles, scat singing, bent horn, pouched cheeks, and light-hearted personality provided some of bebop's most prominent symbols.
