Ballroom dance in triple time (5)
I believe the answer is:
waltz
'ballroom dance in triple time' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for waltz that I've seen before include "German dance" , "Ballroom dance in triple time" , "A flowing melody or dance in triple time" , "Last dance?" , "The 123, 123 ballroom dance" .)
