Which voice has some real tone? (4)
I believe the answer is:
alto
'which voice' is the definition.
I can't tell whether this definition defines the answer.
'some real tone?' is the wordplay.
'some' indicates the answer is hidden within the clue (some parts of the word are used).
'ALTO' can be found hidden inside 'real tone'.
'has' acts as a link.
Can you help me to learn more?
(Other definitions for alto that I've seen before include "Second of four parts (in singing)" , "Woman's singing voice" , "One who sings" , "The highest adult male singing-voice" , "High male singing voice" .)
