Rascal breaks unfinished instrument - can it still make this sound? (7)
I believe the answer is:
vibrato
'this sound?' is the definition.
(vibrato is a kind of sound)
'rascal breaks unfinished instrument can it still' is the wordplay.
I cannot quite see how this works, but
'rascal' could be 'brat' (brat is a kind of rascal) and 'brat' is found in the answer.
This may be the basis of the clue (or it may be nonsense).
'make' acts as a link.
Can you help me to learn more?
(Other definitions for vibrato that I've seen before include "Oscillatory effect" , "Singing effect" , "Rapid pitch variation" , "Rapid alternation in pitch" , "Pulsating effect in instrumental or vocal tone" .)
