Stage dance sequence (4)
I believe the answer is:
step
I believe this clue is a double definition.
'stage' is the first definition.
(I've seen this in other clues)
'dance sequence' is the second definition.
(part of a dance)
(Other definitions for step that I've seen before include "Dance move" , "Single pace" , "Stage - pace" , "Pace; foothold" , "Pest (anag.)" .)
