Musicians playing polyrhythms count at two or more rates simultaneously. Further, they operate their limbs and fingers accordingly.
True, but I wouldn’t call that conscious counting - you’re not literally counting out multiple simultaneous time signatures in your head, it’s done by feel.
It’s done by counting first. You can’t feel if you don’t count.
This is timely as I’m actually new to drumming and teaching myself some basic polyrhythms right now. I’m definitely not capable of actively counting both rhythms at the same time. I’ll count one, play it until I’m not really thinking about it anymore, then play the other one on top of it. After awhile, my arms and legs will just go, my brain isn’t actually counting the rhythms individually but it hears the combined rhythm, basically I just memorize until the point that the polyrhythm syncs up and repeats. I didn’t use them, but there’s also a lot of common “phases” for learning these basic polyrhythms, like “pass the bread and butter” for 3 and 4, again just a tool to let the mind think of one funky rhythm rather than two basic rhythms played at once. Technically, they’re the same rhythm, but the first is easier to conceptualize
Enough a proof that brains are more complex than a single processor calculating one thing at a time.
Furthermore, what about people who had lobotomy done to them? Weird things happen with two halves of the brain (now separate) “thinking” two different things at the same time!
That’s a corpus callosotomy, not a lobotomy.
