Sorry to be a party killer but I've discovered that the song in the OP isn't by John Stump and isn't "Faerie's Aire and Death Waltz". This is what the real sheet music looks like:
It's clearly not the same thing, and if you look at some of the details you can see it's literally just a joke, never intended to actually be played.
The song is really called "U.N. Owen Was Her?" and is the music from some Japanese video game called the
Touhou Project. Still a cool piece of music though.
