Dance follows live jazz (5)
I believe the answer is:
bebop
'jazz' is the definition.
(bebop is a kind of jazz)
'dance follows live' is the wordplay.
'dance' becomes 'bop' (bopping is a kind of dancing**).
'follows' says to put letters next to each other.
'live' becomes 'be' ('be' can be a synonym of 'live').
'bop' after 'be' is 'BEBOP'.
(Other definitions for bebop that I've seen before include "Monk composed this" , "1940s' form of modern jazz" , "kind of jazz" , "Jazzy music style" , "Type of jazz" .)
