Orchestra to transgress, less authentic for an audience? (8)
I believe the answer is:
sinfonia
'orchestra' is the definition.
(I've seen this before)
'transgress less authentic for an audience?' is the wordplay.
'transgress' becomes 'sin' (sinning is a kind of transgressing).
'less authentic' becomes 'phonier' (I've seen this in another clue).
'for an audience?' indicates a 'sounds like' (homophone) clue (as the word might sound to an audience).
'phonier' sounds like 'fonia'.
'sin'+'fonia'='SINFONIA'
'to' acts as a link.
(Other definitions for sinfonia that I've seen before include "Without limit" , "Symphonic music - as if in no (anag)" , "Small orchestra" , "Composition" , "Orchestral piece" .)
