After losing ring, chief has a low sounding voice (4)
I believe the answer is:
bass
'sounding voice' is the definition.
'bass' can be an answer for 'voice' (bass is a kind of voice). I'm unsure of the 'sounding' bit.
'after losing ring chief has a low' is the wordplay.
'after losing ring chief' becomes 'bas' (I can't justify this - if you can you should believe this answer much more).
'a low' says to take the final letters (I've seen 'lowest' mean this (in a down clue, the bottom-most letter)).
The final letter of 'has' is 's'.
'bas'+'s'='BASS'
Can you help me to learn more?
(Other definitions for bass that I've seen before include "A fish, or the lowest pitch in music" , "Freshwater fish and lowest voice" , "Fish; male singing voice" , "Big percussion instrument" , "Deep-voiced male singer" .)
