It’s really something, even in robotic MIDI form. The chromaticism leapt right out at me on first hearing. It’s worth going on a little journey so you understand what chromaticism is and why it’s a big deal. The chromatic scale is the one you get when you play all 12 notes in the Western tuning system, all the notes on the piano or guitar or whatever. The chromatic scale sounds pretty bad. It’s too much information. The notes don’t feel like they’re related in any particular way, like there’s any logic to them.
I am fascinated by the creative potential of “musical theology,” a pre-Enlightenment relic from the tradition in which J.S. Bach thrived. For Bach and his cronies, music theory was a direct extension and reflection of metaphysical and religious truths. The major chord, three notes in one sound, was the trinity; equal temperament (a practical approximation that detunes each note slightly from the mathematical ratios of just intonation) represented the sinning imperfections of humankind, a musical Fall from God-made purity.
