Norwegian composer (5)
I believe the answer is:
grieg
'norwegian composer' is the definition.
(Norwegian composer Edvard Grieg 1843-1907)
This is all the clue.
(Other definitions for grieg that I've seen before include "Composer of incidental music to Peer Gynt, d.1907" , "Norwegian composer (Peer Gynt)" , "Scandinavian composer, d. 1907" , "Composer of the incidental music for Ibsen's Peer Gynt" , "Edvard ---, composer" .)
