Crossword Genius

Audibly criticise acts providing night music (9)

Ross

I believe the answer is:

nocturnes

'night music' is the definition.
(music inspired by night)

I cannot understand how the rest of the clue works.

(Other definitions for nocturnes that I've seen before include "Romantic pieces" , "Compositions popularised by Field and Chopin" , "piano pieces" .)

I've seen this clue in The Guardian.
