"The Bartered Bride" composer (7)
I believe the answer is:
smetana
'the bartered bride composer' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for smetana that I've seen before include "Composer of The Bartered Bride; eats man (anag.)" , "Nineteenth century Czech composer (The Bartered Bride)" , "Bedrich ____, composer of "The Bartered Bride" and "The Kiss"" , "musician" , "maker of notes" .)
