Musician's gift (3)
I believe the answer is:
ear
'musician's gift' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for ear that I've seen before include "Listening organ" , "Head of grain" , "'Give every man thine ..., but few thy voice' (Hamlet)" , "Speculator ignoring British" , "Lend one and listen" .)
