'she' is the definition.

'me repeat myself' is the wordplay.
'me' becomes 'mi' (both are spellings of the musical note).
'repeat' becomes 'm' (I can't justify this - if you can you should believe this answer much more).
'myself' becomes 'I'.
'mi'+'m'+'i'='MIMI'

'makes' is the link.

Can you help me to learn more?
