Low note or notes? (6)

Ross

I believe the answer is:

moolah

I'm a little stuck... Click here to teach me more about this clue!

'or notes?' is the definition.
I can't judge whether this defines the answer.

'low note' is the wordplay.
'low' becomes 'moo' (both can mean to make the noise of a cow).
'note' becomes 'lah' (I've seen this before).
'moo'+'lah'='MOOLAH'

Can you help me to learn more?

(Other definitions for moolah that I've seen before include "dosh" , "money on the streets" , "bread" .)

I've seen this clue in The Independent.
