Vocal number or note sounded (5)
I believe the answer is:
tenor
'vocal' is the definition.
(thesaurus)
'note sounded' is the wordplay.
'note' becomes 'tenner' (a tenner is a 10 pound note).
'sounded' shows a homophone (sound like).
'tenner' sounds like 'TENOR'.
'number or' acts as a link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for tenor that I've seen before include "Placido Domingo, say" , "Carreras, for example" , "Pavarotti, for example" , "Meaning - male singing voice" , "Male singing voice of high pitch" .)
