Water Music composer (1685-1759) (6)
I believe the answer is:
handel
'water music composer' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for handel that I've seen before include "Anglo-German composer" , "Water Music composer, d. 1759" , "German baroque composer" , "Composer of the great ''Messiah''" , "German scorer" .)
