Charm of a quiet ringing of bells (6)
I believe the answer is:
appeal
'charm' is the definition.
(I know that charm can be written as appeal)
'a quiet ringing of bells' is the wordplay.
'quiet' becomes 'p' (music symbol for 'piano', ie soft or quiet).
'ringing of bells' becomes 'peal' (I've seen this in another clue).
'a'+'p'+'peal'='APPEAL'
'of' is the link.
(Other definitions for appeal that I've seen before include "Contest a verdict" , "A crustacean" , "Refer sentence to higher court for review" , "Request for reconsideration" , "Earnest or urgent equest" .)
