Music from number ten, possibly (5)
I believe the answer is:
nonet
'music' is the definition.
(I've seen this before)
'number ten possibly' is the wordplay.
'number' becomes 'no' (abbreviation for 'number').
'possibly' indicates anagramming the letters.
'ten' anagrammed gives 'net'.
'no'+'net'='NONET'
'from' acts as a link.
(Other definitions for nonet that I've seen before include "Band of nine?" , "Piece for nine musicians" , "Music for nine instruments or voices" , "Band's" , "Composition for nine voices" .)
