Criticise rhythmic chanting (3)
I believe the answer is:
rap
I believe this clue is a double definition.
'criticise' is the first definition.
(thesaurus)
'rhythmic chanting' is the second definition.
(Other definitions for rap that I've seen before include "Rhythmic monologue (pop)" , "Knock for par" , "Knock loudly" , "Sharply strike; rebuke" , "Sharp blow; criticism" .)
