Final answer:
Cool jazz is different from bebop in terms of its style, tempo, and improvisation. It is viewed as a reaction to bebop due to its more relaxed and accessible nature.
Step-by-step explanation:
The cool jazz sound is different from bebop in several ways. Cool jazz is characterized by a more relaxed and laid-back style, with a focus on slower tempos, lighter melodies, and softer dynamics. Bebop, on the other hand, is known for its fast and complex melodies, intricate improvisation, and rhythmic complexity.
Cool jazz is viewed as a reaction to bebop because it emerged as a response to the technical virtuosity and complexity of bebop. Musicians felt that bebop had become too inaccessible and wanted to create a more laid-back and listener-friendly style. Cool jazz also incorporated elements from other musical genres such as classical music, blues, and even some elements of popular music.
