Which statement about bebop is true?

Bebop is significant in the history of jazz as it truly revolutionized the genre and laid the groundwork for modern jazz. This style emerged in the 1940s as a reaction against the big band swing music that dominated the previous decade. Bebop introduced complex melodies, advanced harmonies, and intricate rhythms. Musicians like Charlie Parker and Dizzy Gillespie emphasized improvisation and artistic expression, moving away from danceable tunes to a focus on musicianship and creative spontaneity. The influence of bebop can be seen in various modern jazz styles, where its elements are integrated and expanded upon, making it a foundational movement in the evolution of jazz.

In contrast, the other options do not accurately reflect the nature or impact of bebop. While it did not replace swing as the dominant style of dance music, it certainly differentiated itself from it. Bebop also significantly changed the perception of jazz from being primarily entertainment to an art form worthy of serious consideration. Additionally, while individual performance is a hallmark of bebop, it is not solely focused on that; ensemble playing and interaction among musicians are equally important.
