They make music with metal rings (5,5)
I believe the answer is:
brass bands
'they make music' is the definition.
The definition suggests an adverb but the answer is not.
'with metal rings' is the wordplay.
'with' means one lot of letters go next to another.
'metal' becomes 'brass' (brass is a kind of metal).
'rings' becomes 'bands' ('band' can be a synonym of 'ring').
'brass' next to 'bands' is 'BRASS BANDS'.
Can you help me to learn more?
(Another definition for brass bands that I've seen is " Groups of musicians".)
