Performance with arias (5)
I believe the answer is:
opera
'performance with arias' 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 "Drama with singing" , "Staged event" , ""Rigoletto", for example" , "Patience, perhaps" , "La Traviata or Tosca, say" .)
