Include real arrangement of work by Debussy (5,2,4)

I believe the answer is:

clair de lune

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

'work by debussy' is the definition.
The definition suggests a singular noun which matches the answer.

'include real arrangement' is the wordplay.
'arrangement' indicates an anagram.
'include'+'real'='includereal'
'includereal' with letters rearranged gives 'CLAIR DE LUNE'.

'of' acts as a link.

Can you help me to learn more?
