History
Bebop emerged in New York City in the early 1940s, especially in the after-hours clubs and jam sessions where younger musicians pushed against the smoother, more arranged sound of swing. Library of Congress sources describe it as a new jazz language taking shape in that period, with figures such as Charlie Parker, Dizzy Gillespie, Thelonious Monk, and Max Roach helping define its fast tempos, harmonic daring, and small-group intensity. (tile.loc.gov) The style’s early recordings and live scenes made the break clear: Parker’s “Ko Ko” became a kind of manifesto, and the new sound soon set the terms for modern jazz, influencing everything from hard bop to later post-bop explorations. What began as a challenge to the old rules became, quickly, one of jazz’s most durable vocabularies. (loc.gov)
