Echoing musical with two notes raised (9)
I believe the answer is:
imitative
'echoing' is the definition.
(I've seen this before)
'musical with two notes raised' is the wordplay.
'musical' becomes 'evita' (Andrew Lloyd Webber musical).
'with two notes' becomes 'timi' (I can't justify this - if you can you should give a lot more credence to this answer).
'raised' is a reversal indicator (going up in a down clue).
'evita'+'timi'='evitatimi'
'evitatimi' backwards is 'IMITATIVE'.
(Other definitions for imitative that I've seen before include "Following a model" , "Apish, emulative" , "pirated" , "Copying" , "Echoing" .)
