A bum intro, playing French folk music (9)
I believe the answer is:
tambourin
'music' is the definition.
(I know that tambourin is a music)
'a bum intro playing' is the wordplay.
'playing' indicates anagramming the letters.
'a'+'bum'+'intro'='abumintro'
'abumintro' with letters rearranged gives 'TAMBOURIN'.
'french folk' acts as a link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Another definition for tambourin that I've seen is " Folk dance".)
