This is something I did about a year ago in my computer music class. One of my first pieces ever. There are a few troubling spots that I'm aware of. It was a fun piece to do.. The sawtooth wave is the one on the right, considered the evil voice represented with the atonal things going on behind it. The good voice is on the right as a female voice sound (pretty typical). They are apart, giving their own motive alone then you hear both, representing them getting closer to one another. They then move together and meet at a tritone, the ultimate dissonance. A battle is fought and you can tell the rest. I was playing Zelda and the idea came up to do a song like this. It's a pretty cliche piece but anyways, take a listen. Any constructive criticism would be awesome.
Please contact me if you would like to use this in a project. We can discuss the details.
