Group of musicians finds Edward subdued (5)
I believe the answer is:
muted
'subdued' is the definition.
(I've seen this before)
'group of musicians finds edward' is the wordplay.
'group of musicians finds' becomes 'mu' (I can't justify this - if you can you should give a lot more credence to this answer).
'edward' becomes 'ted'.
'mu'+'ted'='MUTED'
Can you help me to learn more?
(Other definitions for muted that I've seen before include "Kept quiet" , "In a softened tone" , "Muffled, subdued" , "Subdued; not bright" , "Hushed, dulled or deadened" .)
