Note from one kind of singer heard (6)
I believe the answer is:
tenner
'note' is the definition.
(a tenner is a 10 pound note)
'one kind of singer heard' is the wordplay.
'one kind of singer' becomes 'tenor'.
'heard' shows a homophone (sound like).
'tenor' is a homophone of 'TENNER'.
'from' is the link.
(Other definitions for tenner that I've seen before include "Cash note" , "Ten pound note (colloq.)" , "Monetary note" , "Heard bell" , "Two fivers" .)
