Resist trend, one that's hitting the high notes (12)
I believe the answer is:
countertenor
'one that's hitting the high notes' is the definition.
I can't tell whether this definition defines the answer.
'resist trend' is the wordplay.
'resist' becomes 'counter'.
'trend' becomes 'tenor' (I've seen this in another clue).
'counter'+'tenor'='COUNTERTENOR'
Can you help me to learn more?
(Other definitions for countertenor that I've seen before include "Singer" , "Highest male singing voice" , "he'll sing" , "being highly vocal" , "Adult male with an alto voice" .)
