Communication by Queen in Melody Maker (8)

'melody maker' is the definition.
I don't know anything about this answer so I can't tell whether it can be defined by this definition.

'communication by queen' is the wordplay.
I cannot really see how this works, but
'communication' could be 'message' (message is a kind of communication) and 'message' is found within the answer.
'queen' could be 'r' (abbreviation for regina, e.g. in ER ) and 'r' is located in the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).

'in' is the link.

Can you help me to learn more?
