Orchestral work by Ravel (6)
I believe the answer is:
bolero
'orchestral work by ravel' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for bolero that I've seen before include "Spanish dance - item of clothing" , "Upper garment or music piece by Ravel" , "Rob Leo of his short jacket" , "Short open jacket - Ravel composition" , "Woman's short jacket" .)
