More atonal business. Or is it?
20th Century Expressionists sought ways to express through music that didn't rely on our (I believe) natural tendency to organize the experience around a tone center. One way was to make the rules: "no repeating a note until you've done all 12 of them, and you must do your intervals in the same order throughout the piece."
That's all well and good, but I think we key into sonorities. Resonances. Combinations of notes that interact with one another in particular ways.
So, enough. I followed the rules, but selected an order for my notes that yielded stuff I thought sounded sonorous. Turns out it almost implies chord function. This is a good start, a proof-of-concept. More would have to be done to this to turn it into "music." I think I will.
