Gets one's engine singing the right notes (5)

'right notes' is the definition.
The definition and answer can be both related to communication as well as being plural nouns.
Perhaps you can see an association between them that I can't see?

'gets one's engine singing the' is the wordplay.
I cannot really see how this works, but
'the' could be 't' (the is pronounced as a 't' sound in some dialects) and 't' is found within the answer.
'one' could be 'un' (northern English dialect form of 'one') and 'un' is located in the answer.
The remaining letters 'es' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?
