Jazz Discussion

I don’t know how to handle this Art question and need guidance. 1. Compare/contrast cool jazz and hard bop, by explaining three  musical characteristics of each style. Identify two key innovators of  each style, and the geographic associations of each style. How did the  phenomenon of “West Coast Jazz” and its racial coding as “white” make  the African-American jazz scene in Los Angeles invisible? 2.  Explain how the approach to jazz called modalism was unique and  distinctly different, compared to other post bop styles in the 1950s.  Identify the artist and title of the influential album that launched the  modal jazz scene.
