Artist bringing in name for mass performance piece (5)
I believe the answer is:
nonet
'piece' is the definition.
(I have seen 'musical piece' mean 'nonet' so perhaps 'piece' could also mean 'nonet')
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for nonet that I've seen before include "Composition for nine players" , "baseball team" , "Music for nine instruments or voices" , "Band's" , "Band of nine?" .)
