Stan Getz and the Oscar Peterson Trio

Bebop is a modern jazz style characterized by fast tempos, intricate melodies, and harmonically advanced improvisation. It moved jazz from dance-oriented big-band music to art-focused small-ensemble performance, prioritizing virtuosity and spontaneous creativity. Typical bebop groups are quintets or quartets featuring trumpet, alto or tenor saxophone, piano, double bass, and drums. The music emphasizes asymmetrical phrasing, extended chords and substitutions, and contrafacts—new melodies written over the chord changes of popular songs. Rhythm sections center time on the ride cymbal, with the bass walking and the drummer "dropping bombs" on snare and bass drum. Melodies are angular and chromatic, and soloists outline rapidly shifting harmonies with bebop scales, enclosure tones, and altered dominants.
