Carmen and Salome (6)
I believe the answer is:
operas
'carmen and salome' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for operas that I've seen before include "Dramas set to music" , "Plays in which the words are sung" , "Musical dramas" , "Nabucco and Tosca" , "La Traviata, Aida" .)
