Tell the scorer (7)
I believe the answer is:
rossini
'the scorer' is the definition.
(I've seen this before)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for rossini that I've seen before include "Italian opera composer" , "he produced harmony" , "He composed operas" , "whose barber was in Seville" , "Gioacchino ---, It. composer" .)
