Be repulsive as you dance round the piano (5)
I believe the answer is:
repel
'be repulsive as you' is the definition.
I can't tell whether this definition defines the answer.
'dance round the piano' is the wordplay.
'dance' becomes 'reel' (reel is a kind of dance).
'round' means one lot of letters goes inside another.
'the piano' becomes 'p'.
'reel' going around 'p' is 'REPEL'.
Can you help me to learn more?
(Other definitions for repel that I've seen before include "See off" , "Reject" , "Drive back, rebuff" , "Put off - disgust" , "Drive back or disgust" .)
