Ring for the musicians (4)
I believe the answer is:
band
This clue is a double definition.
'ring' is the first definition.
(synonyms)
'musicians' is the second definition.
(group of musicians)
'for the' is the link.
(Other definitions for band that I've seen before include "Strip, belt; playing group" , "Pop group; stripe" , "Zone; group" , "A collection of musicians in ring" , "troop" .)
