Does he write notes hoping to make people better? (6,2,5)

'does he' is the definition.
The answer and definition can be both related to communication as well as being singular nouns.
Maybe there's a link between them I don't understand?

'write notes hoping to make people better?' is the wordplay.
I cannot quite see how this works, but
'notes' could be 'music' (a piece of music is made up of musical notes) and 'music' is found in the answer.
'to' is found in the answer.
'make' could be 'do' (synonyms) and 'do' is present in the answer.
This may be the basis of clue (or it may be nonsense).

Can you help me to learn more?
