Sonnet about ensembles (6)
I believe the answer is:
nonets
'ensembles' is the definition.
I know nothing about this answer so I cannot tell whether this works.
'sonnet about' is the wordplay.
'about' indicates an anagram.
'sonnet' anagrammed gives 'NONETS'.
Can you help me to learn more?
(Other definitions for nonets that I've seen before include "Group of players" , "musical pieces" , "Compositions for nine players" , "Pieces of music for groups of nine" , "Compositions for nine performers" .)
