Tenor in touch? (5)
I believe the answer is:
sense
This clue is a double definition.
'tenor' is the first definition.
(thesaurus)
'touch?' is the second definition.
(touch is a kind of sense)
'in' acts as a link.
(Other definitions for sense that I've seen before include "Pick up point" , "Gumption -- feeling" , "Be vaguely aware of" , "Perceive; meaning" , "Could be hearing" .)
