Concerto finale, often (5)
I believe the answer is:
rondo
'concerto finale often' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for rondo that I've seen before include "noted work" , "Donor (anag) - piece of music" , "Music with repeated refrains" , "Type of movement" , "Musical work" .)
