Closing musical passage (4)
I believe the answer is:
coda
'closing musical passage' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for coda that I've seen before include "Conclusion of work" , "Closing section of a musical composition" , "Closing part of a musical composition" , "Closing bars (mus.)" , "Final section" .)
