A wad of notes - bread! (4)
I believe the answer is:
roll
This clue could be a double definition.
'a wad' is the first definition.
(thesaurus)
'notes bread' is the second definition.
'roll' can be an answer for 'bread' (roll is a kind of bread). I'm not sure about the 'notes' bit.
'of' is the link.
Can you help me to learn more?
(Other definitions for roll that I've seen before include "movement of ship" , "Small rounded bread" , "start a revolution" , "Revolve - piece of bread" , "Sound of a drum or a list of names" .)
