Just for fun, here's a piece I wrote quite a few years ago. Yeah yeah, it's not 100% authentic, but you get the idea. :) Just intonation is a kind of musical tuning which uses rational numbers for the intervals of the scale. Some people say this tuning has a mathematical purity, some would even go as far as to say that it has DNA healing properties but I wouldn't be inclined to agree. In this case, I've used a 13-note just scale to make microtonal chiptune music in a drum'n'bass style. It's boss music for an alternative music theory.
