Bebop

In the mid-1940s, a generation of young jazz musicians broke away from the more commercial dance sounds of big band swing to create the more cerebral, improvisation-oriented style known as bebop.  In addition to focusing on smaller groups of musicians, most often quartets or quintets, bebop differed from swing in that the soloists engaged in a more abstract form of chord-based (rather than melodic) improvisation, often dispensing with the melody altogether after the first chorus.  Bebop also introduced new levels of dissonance into the music.

Bebop’s early leading lights included trumpeters Dizzy Gillespie and Clifford Brown, saxophonist Charlie Parker, pianists Bud Powell and Thelonious Monk, bassist Ray Brown, and drummer Max Roach.  They were soon joined by such key innovators as trumpeter Miles Davis, bassist Charles Mingus, and saxophonists John Coltrane and Sonny Rollins.

The radical new style was initially controversial amongst some listeners and musicians.  By the ’50s, though, bebop was firmly established as the source of most of jazz’s creative advances, and it has remained a vital foundation for many of jazz’s innovations in the decades since.
