John Birks "Dizzy" Gillespie (pronounced /ɡɨˈlɛspi/; October 21, 1917 – January 6, 1993) was an American jazz trumpet player, bandleader, singer, and composer dubbed "the sound of surprise".
Together with Charlie Parker, he was a major figure in the development of bebop and modern jazz. He taught and influenced many other musicians, including trumpeters Miles Davis, Fats Navarro, Clifford Brown, Arturo Sandoval, Lee Morgan, Jon Faddis and Chuck Mangione.
Allmusic's Scott Yanow wrote that "Dizzy Gillespie's contributions to jazz were huge. One of the greatest jazz trumpeters of all time (some would say the best), Gillespie was such a complex player that his contemporaries ended up copying Miles Davis and Fats Navarro instead, and it was not until Jon Faddis's emergence in the 1970s that Dizzy's style was successfully recreated . . . Arguably Gillespie is remembered, by both critics and fans alike, as one of the greatest jazz trumpeters of all time.
