Dizzy Gillespie on traditional Afro-Cuban rhythms. Gillespie was introduced to Chano Pozo in 1947 by Mario Bauza, a Latin jazz trumpet player. Chano Pozo became Gillespie's conga drummer for his band. Gillespie also worked with Mario Bauza in New York jazz clubs on 52nd Street and several famous dance clubs such as the Palladium and the Apollo Theater in Harlem. They played together in the Chick Webb band and Cab Calloway's band, where Gillespie and Bauza became lifelong friends. Gillespie helped develop and mature the Afro-Cuban jazz style. Afro-Cuban jazz was considered bebop-oriented, and some musicians classified it as a modern style.
Jazz trombone driving force of this stylistic movement was J.J. Johnson, who is considered by some to be one of the most important figures in jazz trombone history. He followed the influences of bebop jazz innovators Charlie Parker and Dizzy Gillespie while adding his own, smooth, slower form of playing over the fast tracks of bebop. Typically when playing jazz music, it is preferred to be played on a standard small or medium bore tenor trombone with no extra attachments, as it will give the brightest sound and is more comfortable to play for longer periods of time in the extreme ranges
