Musical talent in Renaissance arises (3)
I believe the answer is:
ear
'musical talent' is the definition.
(as in 'having an ear' for music)
'in renaissance arises' is the wordplay.
'in' indicates a hidden word.
'EAR' is hidden within 'renaissance arises'.
(Other definitions for ear that I've seen before include "Seed-bearing part of corn" , "Organ involved with balance" , "organ with drum" , "Auricle" , "Part of a cereal plant containing the seeds" .)
