"Parsifal" composer
I believe the answer is:
wagner
'parsifal composer' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for wagner that I've seen before include "Richard . . . . . . composer of 'The Flying Dutchman' and 'Lohengrin'" , "Composer of ''The Flying Dutchman'' etc" , "German composer of The Ring Cycle" , "Tannhauser composer" , "Noted German" .)
