Final answer:
Bebop altered the jazz culture by fostering a subculture that valued non-conformity and anti-materialism, transforming jazz clubs into centers for individualism and improvisation.
Step-by-step explanation:
Bebop significantly changed the culture of jazz during the late 1940s by introducing a complex and highly improvisational style that diverged from the more structured and dance-oriented swing music that preceded it. This new jazz form fostered a subculture of 'hipsters' who embraced the spontaneity and sophistication of bebop, which reflected their non-conformist and anti-materialistic values. Jazz clubs became hubs for this emergent counterculture, epitomizing a broader societal shift towards improvisation, individual expression, and the questioning of mainstream norms. The Beat Generation later emerged during the 1950s, drawing inspiration from the radical politics and unstructured music that bebop had helped popularize.
