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

'greatly enrage' is the definition.
'incense' can be an answer for 'enrage' (I've seen this before). I'm not certain of the 'greatly' bit.

'one note unfortunate scene' is the wordplay.
'one note' becomes 'in' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'unfortunate' indicates an anagram.
'scene' anagrammed gives 'cense'.
'in'+'cense'='INCENSE'

Can you help me to learn more?

(Other definitions for incense that I've seen before include "Enrage - fragrant material for burning" , "Church perfume" , "Material with fragrant fumes" , "Send bananas" , "Substance burned for its sweet smell" .)
