Austrian composer of The Creation (5)
I believe the answer is:
haydn
'austrian composer of the creation' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for haydn that I've seen before include "Composer of over 100 symphonies" , "Joseph -, Austr. composer (Farewell Symphony)" , "Creation composer" , "The Seasons composer" , "Joseph -, prolific eighteenth to nineteenth century Austrian composer" .)
