The tradition & historical record
2 min read · 1 sourceBebop or bop is a style of jazz developed in the early to mid-1940s in the United States. It is characterized by a fast tempo, complex chord progressions—with rapid chord changes, changes of key, angular melodies and substitute chords—along with virtuosic improvisation based on a combination of harmonic structure, scales, and occasional references to the melody. Bebop developed as the younger generation of jazz musicians expanded the creative possibilities of jazz beyond the popular, dance-oriented swing music-style to a new "musician's music" that was not as danceable and demanded close listening. As bebop was not intended for dancing, it enabled the musicians to play at faster tempos. Bebop musicians explored advanced harmonies, complex syncopation, altered chords, extended chords, chord substitutions, asymmetrical phrasing, and intricate melodies. Bebop groups used rhythm sections in a way that expanded their role. Whereas the key ensemble of the swing music era was the big band of 16–18 musicians playing in an ensemble-based style, the classic bebop group was a small combo that consisted of saxophone (alto or tenor), trumpet, piano, guitar, double bass, and drums playing music in which the ensemble played a supportive role for soloists.
