Form of jazz that doesn't need be! (5)
I believe the answer is:
bebop
This might be a double definition.
'form' is the first definition.
(I have seen 'Form of jazz ' mean 'bebop' so perhaps 'form' could also mean 'bebop')
'jazz that doesn't need be' is the second definition.
'bebop' can be an answer for 'jazz' (bebop is a kind of jazz). I'm not sure about the remainder of the definition.
'of' is the link.
Can you help me to learn more?
(Other definitions for bebop that I've seen before include "1940s' form of modern jazz" , "Fast, complex jazz" , "Monk composed this" , "kind of jazz" , "Jazz genre" .)
