Movement to music (5)
I believe the answer is:
dance
'movement to music' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for dance that I've seen before include "Eg, foxtrot or tango" , "the twist, perhaps?" , "Eg, waltz, foxtrot" , "Waltz, say" , "Step to music" .)
