One who gets high? (7)
I believe the answer is:
soprano
'one who gets high?' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for soprano that I've seen before include "Producer of high-pitched sounds" , "Norman, perhaps" , "(Singer of) the highest vocal range" , "Singer of high notes" , "Singer who aims high" .)
