Heard notes from operatic singers (6)
I believe the answer is:
tenors
'operatic singers' is the definition.
'tenors' can be an answer for 'singers' (tenor is a kind of singer). I am unsure of the 'operatic' bit.
'heard notes' is the wordplay.
'heard' shows a homophone (sound like).
'notes' becomes 'tenners' (ten pound notes).
'tenners' sounds like 'TENORS'.
'from' is the link.
Can you help me to learn more?
(Other definitions for tenors that I've seen before include "Opera singers" , "Male singing voices" , "Male singers from Reston" , "Male singers with high register" .)
