Making sound spoils instrument (4)
I believe the answer is:
lute
'instrument' is the definition.
(I know that Lute is a instrument)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for lute that I've seen before include "Plucked, pear-shaped instrument" , "Old stringed instrument with a pear-shaped body" , "Play instrument" , "clay" , "Ancient stringed instrument" .)
