Sound made by a band (4)
I believe the answer is:
ring
This clue is a double definition.
'sound' is the first definition.
(ringing is a kind of sounding)
'a band' is the second definition.
(synonyms)
'made by' acts as a link.
(Other definitions for ring that I've seen before include "token of love" , "Form circle around" , "sign of union?" , "Make sound like phone" , "Toll" .)
