Impressionist notes top tip from Cézanne (5)

I believe the answer is:

mimic

I'm a little stuck... Click here to teach me more about this clue!

'impressionist' is the definition.
(I've seen this before)

'notes top tip from cezanne' is the wordplay.
'notes top' becomes 'mimi' (I am not sure about this - if you are sure you should believe this answer much more).
'tip from' suggests taking the first letters.
The first letter of 'cezanne' is 'c'.
'mimi'+'c'='MIMIC'

Can you help me to learn more?

(Other definitions for mimic that I've seen before include "Imitate satirically" , "parrot" , "Act like" , "Copy (voice, mannerisms)" , "Impersonator" .)
