Beat to stir up dancing (8)
I believe the answer is:
outstrip
'beat' is the definition.
(outstripping is a kind of beating)
'to stir up dancing' is the wordplay.
'dancing' indicates an anagram.
'to'+'stir'+'up'='tostirup'
'tostirup' with letters rearranged gives 'OUTSTRIP'.
(Other definitions for outstrip that I've seen before include "Exceed; move faster than" , "Move faster than and overtake" , "eclipse" , "Leave behind" , "Go far ahead of" .)
