Reportedly criticise change in piano piece, perhaps (8)
I believe the answer is:
nocturne
'piece perhaps' is the definition.
'nocturne' can be an answer for 'piece' (thesaurus). I'm not certain of the 'perhaps' bit.
'reportedly criticise change in piano' is the wordplay.
I cannot quite understand how this works, but
'reportedly' could be 'e' (I've seen this in other clues) and 'e' is found within the answer.
'change' could be 'turn' (turn is a kind of change) and 'turn' is located in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for nocturne that I've seen before include "Dreamy piano peace popularised by Chopin" , "Short romantic piece of music - in the night?" , "Pensive lyrical piece of music" , "Short romantic musical composition" , "Piece of dreamy music" .)
