Bebop was born in the night clubs of Harlem, when young musicians rebelled against commercial swing. They accelerated the tempos, complicated the harmony (chord substitutions, upper extensions), and made melodies sharp, angular, and built on virtuosic improvisation.
Its chief creators were the alto saxophonist Charlie Parker (“Bird”) and the trumpeter Dizzy Gillespie, along with the pianist Thelonious Monk. Bebop transformed jazz from dance entertainment into a serious art for attentive listening — and defined the language of modern jazz for decades to come. Alongside Parker and Gillespie it was shaped by the pianist Bud Powell and the drummer Max Roach, and the very name “bop” imitates the characteristic rhythmic ending of a phrase.
