Concerto movement (5)
I believe the answer is:
rondo
'concerto movement' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for rondo that I've seen before include "Music form with recurring theme" , "Musical piece with a recurring theme" , "part of a sonata" , "Piece of music with repeated refrain" , "noted work" .)
