Leaves with bags of Quavers? (5,5)
I believe the answer is:
sheet music
'of quavers?' is the definition.
The definition suggests a singular noun which matches the answer.
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for sheet music that I've seen before include "printed notepaper?" , "Printed part for performer" , "Leaves with scores" , "score" .)
