Heard note from male voice (5)
I believe the answer is:
tenor
'male voice' is the definition.
(I've seen this before)
'heard note' is the wordplay.
'heard' indicates a 'sounds like' (homophone) clue.
'note' becomes 'tenner' (a tenner is a 10 pound note).
'tenner' is a homophone of 'TENOR'.
'from' acts as a link.
(Other definitions for tenor that I've seen before include "General course - male singer" , "High male singing voice like Pavarotti" , "Meaning - male singing voice" , "General meaning of an utterance" , "Eg, Placido Domingo" .)
