Player whose voice hasn’t broken? (5)
I believe the answer is:
piper
'player' is the definition.
(piper is a kind of player)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for piper that I've seen before include "John --, 20th century English artist" , "eg Flautist" , "Bagpipes player" , "Highland instrumentalist" , "One plays" .)
