Clangers, perhaps? (5)
I believe the answer is:
bells
'clangers' is the definition.
(things which make clanging noises)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for bells that I've seen before include "Chimes" , "Summoned by -- (Betjeman)" , "Musical instruments" , "Ringing instruments" , "Those ringing in the New Year" .)
