Singer put right after wrong note (5)
I believe the answer is:
tenor
'singer' is the definition.
(tenor is a kind of singer)
'put right after wrong note' is the wordplay.
'put right' becomes 'r' (I've seen this in other clues**).
'after' is a charade indicator (letters next to each other).
'wrong' is an anagram indicator.
'note' with letters rearranged gives 'teno'.
'r' after 'teno' is 'TENOR'.
(Other definitions for tenor that I've seen before include "direction" , "Caruso or Domingo" , "theme" , "Singer; drift" , "Male 17" .)
