Record showing the range of a singer's voice (8)
I believe the answer is:
register
This clue could be a double definition.
'record showing' is the first definition.
'register' can be an answer for 'record' (registering is a kind of recording). I'm not sure about the 'showing' bit.
'range of a singer's voice' is the second definition.
'register' can be an answer for 'range' (register is a kind of range). I am not certain of the 'of a singer's voice' bit.
'the' acts as a link.
Can you help me to learn more?
(Other definitions for register that I've seen before include "Obituary" , "Annals" , "Log" , "part of our paper" , "(Put one's name down on) list" .)
