They are involved in keeping tempo. I left that part out to simplify the explanation

Especially because the cerebellum has so many different functions. It's obviously involved to a degree. I would expect SM players to have particularly developed portions of the cerebellum, but the Cerebellum does coordinate fluidity and quality of motion as I said before, and these functions are largely irrelevant and it could explain Arch0wl's anecdote (though to be fair, I question the validity of said anecdote. I highly doubt SM players are bad dancers. they're just untrained dancers)

The truth of the matter is that most of your brain would be activate while playing, for example, areas of the frontal lobe and areas involved with memory (hippocampus), along with many other motor pathways. I would expect, however, that the areas I mentioned would be lit up like a wild fire though on an MRI and would dominate most of the neural resources that go into being a good player.
