Produced some sombre dirges (4)
I believe the answer is:
bred
'produced' is the definition.
(breeding is a kind of producing)
'some sombre dirges' is the wordplay.
'some' indicates the answer is hidden within the clue (some parts of the word are used).
'BRED' can be found hidden inside 'sombre dirges'.
(Other definitions for bred that I've seen before include "Generated" , "Gave rise to" , "Reared" , "Propagated, raised" , "Nurtured" .)
