Singer with the general idea (5)
I believe the answer is:
tenor
I believe this is a double definition.
'singer' is the first definition.
(tenor is a kind of singer)
'the general idea' is the second definition.
(I've seen this in another clue)
'with' is the link.
(Other definitions for tenor that I've seen before include "Higher male voice" , "High voice - low bell" , "Placido Domingo, say" , "Eg, Placido Domingo" , "direction" .)
