This is, with "At Zanarkand", one of my all-time favourite compositions of Nobuo Uematsu. Unlike "At Zanarkand", though, this is not a piano only piece (which is my instrument) but a multi instrumental piece.
Note that it covers only the "rhythmic" (?) 12-string guitar and melody; the bass, the other 12-string guitar and the bass are not covered by it.
I believe it is pretty accurate, but I may have made mistakes so feel free to point them out! Also, any potential improvement to the sheet is welcome.
