Kettledrums (7)
I believe the answer is:
timpani
'kettledrums' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for timpani that I've seen before include "Features of kitchen" , "Tina Pim has a set of kettle drums" , "Main pit (anag) - drums" , "Something making drumming noise" , "Mini tap on a large drum" .)
