Nice! Have you looked at Indian ragas and the scales/modes behind those? That was fun for me, coming from a western music background.

Hello fellow Bronie.

Since you're mentioning both linguistics and music theory - did you know that the music of Avatar was originally supposed to be completely different, essentially an alien counterpart to tribal music? I'd love to hear what they started producing, but afaik nothing was ever released. Still, there are some interesting videos on this topic!
