Quiet chanteuse not loud? Certainly not (5)
I believe the answer is:
piano
'quiet chanteuse' is the definition.
'piano' can be an answer for 'quiet' (I've seen this before). I'm unsure of the 'chanteuse' bit.
'loud? certainly not' is the wordplay.
'loud?' becomes 'pia' (I am not sure about this - if you are sure you should believe this answer much more).
'certainly not' becomes 'no'.
'pia'+'no'='PIANO'
'not' is the link.
Can you help me to learn more?
(Other definitions for piano that I've seen before include "entertain with this softly" , "Stringed instrument - to be played quietly" , "In music, soflty" , "In musical notation, this means softly" , "Soft - musical instrument" .)
