Push back piano and dance round (5)

I believe the answer is:
repel
'push back' is the definition.
(synonyms)
'piano and dance round' is the wordplay.
I cannot really understand how this works, but
'piano' could be 'p' (musical abbreviation) and 'p' is present in the answer.
'dance' could be 'reel' (reel is a kind of dance) and 'reel' is found within the remaining letters.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for repel that I've seen before include "Turn away" , "Drive back or away" , "Deflect" , "Reject" , "Fight off - drive back" .)
