Discovered around 2005 thanks to a software extracting video game's sounds, this unreleased track from Masashi Hamauzu for Final Fantasy X might even never appear in the game. It sounds remotely related to the soundtrack song "Illusion", hence its name.

The original song can be heard here (rare record, hot stuff!)

10 years down the line, the able ears of my friend Katchum have at last pierced the mystery of this fantastic harmony. I've put it in sheet music and proposed chord notations.


(On the second page i've not cleaned the alterations (# and b) because I'm bad at that I thought the pitch issue could be solved and then repeat the first page content..)

One bug remains clear, and that might be the reason why the music would not be used in the game: each repetition of the melody lowers the pitch by a semitone.... that means that as the music goes on and on.. the pitch would dip lower and lower.. too bad! (that also doesn't help musicians playing it)
