Does the tango (6)
I believe the answer is:
dances
'does the tango' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for dances that I've seen before include "Can-can, cha-cha etc" , "Moves to music" , "Eg, tango and samba" , "Set movements to music" , "Balls" .)
