Oddly Compelling Visualizations Of CGI Musical Instruments

I remember watching Animusic videos on PBS in the early 2000s. I was always vaguely fascinated by them, even though the graphics looked kind of cheesy. I like the idea that every single note in the composition is supposed to be produced by a specific collision, like a ball bouncing on a percussion instrument. Also, where is this supposed to be taking place? Weird pneumatic pipe/music room? Imagination land? Who knows.
