Maybe Bo-peep provides some jazz (5)
I believe the answer is:
bebop
'some jazz' is the definition.
(bebop is a kind of jazz)
'maybe bo-peep provides' is the wordplay.
'provides' indicates a hidden word.
'BEBOP' is hidden within 'maybe bo peep'.
(Other definitions for bebop that I've seen before include "1940s' jazz characterised by virtuosity" , "Form of modern jazz from about 1940" , "Jazz-style dance music of the 1940s" , "music played in jazz club" , "Fast, complex jazz" .)
