I am intrigued by this map I just came across, thanks to Jon Harnum (who would probably thank Daniel Levitin.) I have the book this map comes from, and have picked it off my shelf way too many times in the past, and have sat down to read only to get distracted with whatever shiny object comes flittering across my desk, never getting past the intro to the intro. Now I feel compelled to bite the bullet and dig into it so that I can discover in greater detail just how much of our brain is stimulated by the act of performing music. I’ll get back to you to tell you what I’ve found.
