Work in the music business (4)
I believe the answer is:
opus
This clue could be a double definition.
'work' is the first definition.
(an opus is an artistic work)
'music business' is the second definition.
Although both the answer and definition are singular nouns, I can't see how one could define the other.
'in the' is the link.
Can you help me to learn more?
(Other definitions for opus that I've seen before include "Musical piece" , "Work of 25 perhaps" , "Composition - magnum __" , "Major work" , "Musical composition in the soup" .)
