Music and the sound of bells (6)
I believe the answer is:
jingle
'sound of bells' is the definition.
'jingle' can be an answer for 'sound' (thesaurus). I'm not sure about the 'of bells' bit.
'music and' is the wordplay.
I cannot really see how this works, but
'music' could be 'g' and 'g' is present in the answer.
'and' could be 'n' (common abbreviation for 'and') and 'n' is present in the answer.
This explanation may well be incorrect...
'the' acts as a link.
Can you help me to learn more?
(Other definitions for jingle that I've seen before include "Tune for advertisement" , "Catchy advertising tune - Pickwick Papers character" , "Advertising melody" , "upset Pickwick" , "Ditty" .)
