Dancers aren't normally trained in music theory. Percussionists are but, having studied modern drums for five years at a conservatory, I can tell you with some confidence that most drummers don't know music theory, because they don't really need it. Because most of music theory has nothing to do with percussions. Why do I need to know harmony to play the drums? So, bad example. A better example would be the intonarumori by Luigi Russolo: https://en.wikipedia.org/wiki/Intonarumori https://en.wikipedia.org/wiki/Intonarumori But the truth is that this kind of wild experimentation with the limits of musicality has never caught up in the same way as modern art has. There is possibly a reason for that. I suspect that it's far easier to ignore something Duchamp's fountain than Russolo's instruments... just because the latter make noise and you can't stop hearing it unless you run away. Btw, I heard some recordings of the intonarumori at a modern art museum in Switzerland, and I thought they were actually ... pleasant? In some sense. But then I find Cannibal Corpse pleasant so I probably have uncommon tastes (though not rare).
