Singer’s delivery of note (5)
I believe the answer is:
tenor
This clue could be a double definition.
'singer's' is the first definition.
(tenor is a kind of singer)
'delivery of note' is the second definition.
'tenor' can be an answer for 'note' (thesaurus). I'm unsure of the 'delivery of' bit.
Can you help me to learn more?
(Other definitions for tenor that I've seen before include "General meaning of a male voice" , "range of 14 across [GIGLI]" , "Male singer with high register" , "Male singing voice of high pitch" , "Drift of thought" .)
