First of all, if you don't know what a tritone or 7th is, then you probably won't understand the title... or half this description. But don't worry! There's always wikipedia :)

Anyways, this song was made using mostly intervals of a tritone and of major 7ths. I also ended up using minor seconds. I purposely made it to step out of the box. It took me maybe a couple hours, and is obviously plain in it's recording. But it's a really odd and kinda cool piece.

Anyways, I hope you like it. I didn't use any other intervals than the ones I mentioned I don't think.
