John Birks "Dizzy" Gillespie ( ghih-LES-pee; October 21, 1917 – January 6, 1993) was an American jazz trumpeter, bandleader, composer, educator and singer. He was a trumpet virtuoso and improviser, building on the virtuosic 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.
