Ruled out note in introduction to Debussy's first (9)

I believe the answer is:

precluded

'ruled out' is the definition.
('preclude' can be a synonym of 'rule out')

'note in introduction to debussy's first' is the wordplay.
'note' becomes 'c' (musical note).
'in' is an insertion indicator.
'introduction' becomes 'prelude' (I've seen this before**).
'first' says to take the initial letters.
The initial letter of 'debussy' is 'd'.
'c' put within 'prelude' is 'preclude'.
'preclude'+'d'='PRECLUDED'

(Another definition for precluded that I've seen is " Ruled out".)

I've seen this clue in The Telegraph.
