Job for a musician (3)
I believe the answer is:
gig
'job for a musician' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for gig that I've seen before include "A single musical performance - it's a palindrome" , "Horse carriage - performer's single booking" , "A palindromic single performance" , "Live musical performance" , "A one-night entertainment" .)
