Bird making some fine music (3)
I believe the answer is:
emu
'bird' is the definition.
(emu is a type of bird)
'some fine music' is the wordplay.
'some' indicates a hidden word (some parts of the word are used).
'EMU' is hidden in the letters of 'fine music'.
'making' acts as a link.
(Other definitions for emu that I've seen before include "Ostrich-like bird" , "Ratite" , "Physics unit" , "Large Australian flightless bird" , "Bird of tremulous kind" .)
