How did bebop differ from earlier jazz styles like swing?

Bebop distinguished itself from earlier jazz styles like swing through its emphasis on improvisation, complex harmonies, and intricate melodies. Unlike swing, which often prioritized a smooth, danceable rhythm and larger ensembles, bebop shifted the focus to small groups of musicians who showcased highly skilled solo improvisation. The harmonic structures in bebop became more elaborate, employing extended chords and unexpected chord changes, which provided a richer palette for improvisers.

Bebop's tempo was generally faster than swing, allowing for rapid-fire solos that highlighted the virtuosity of musicians. While swing was heavily oriented towards dance, bebop was more about the artistic expression of the musician, making it less common for audiences to dance to this style. Vocal arrangements were not a hallmark of bebop; instead, instrumental prowess took center stage, allowing soloists to experiment with new ideas and technical proficiency. Overall, the complexity and spontaneity of bebop represented a significant artistic evolution in jazz.
