Male singer’s general drift (5)
I believe the answer is:
tenor
This clue is a double definition.
'male singer's' is the first definition.
(I've seen this before)
'general drift' is the second definition.
(I've seen this in another clue)
(Other definitions for tenor that I've seen before include "Purport" , "High voice - low bell" , "Eg, Placido Domingo" , "General meaning of an utterance" , "General drift or meaning" .)
