Paper money produced by musician (5)
I believe the answer is:
'paper money' is the definition.
(I've seen this before)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for notes that I've seen before include "Brief written records" , "Observes; short comments" , "Short written messages" , "Memos; observes" , "Paper money" .)
