Note money expanded extensively (3,3,4)
I believe the answer is:
far and wide
'extensively' is the definition.
(I've seen this in another clue)
'note money expanded' is the wordplay.
I cannot quite understand how this works, but
'note' could be 'fa' (fourth note in sol-fa notation: doh, ray, me...) and 'fa' is located in the answer.
'money' could be 'rand' (I've seen this before) and 'rand' is found in the answer.
The remaining letters 'wide' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for far and wide that I've seen before include "Extensive" , "Everywhere" .)
