Adapt a melody for the audience (6)
I believe the answer is:
attune
'adapt' is the definition.
(I've seen this in another clue)
'a melody for the audience' is the wordplay.
I cannot quite see how this works, but
'a' is present in the answer.
'melody' could be 'tune' (synonyms) and 'tune' is located in the answer.
'the' could be 't' (the is pronounced as a 't' sound in some dialects) and 't' is found in the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for attune that I've seen before include "Harmonize or adapt, to matter or idea" , "Bring into harmony" , "Harmonise or adapt, say mind to idea" , "Bring into musical accord" , "Adjust (to a situation)" .)
