Grammy Award category (5)
I believe the answer is:
opera
'grammy award category' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for opera that I've seen before include "Falstaff, say" , "works in Latin" , "The Magic Flute, say" , "Eg, The Magic Flute" , "Patience, perhaps" .)
