Answer 2

I think the answer is bebop or bop. This is also known as rebop. This genre is often used by many African Americans during the Swing Era. It is composed with the main theme and the head theme. It is also layered with extended solos to make the music more dynamic. In this way, it would add more flavor to head theme. Bebop music had evolve thru time and continues to improvise.
