When I was a dance beginner I wanted to be more analytic about it. Surely one could write it all down and visualize and think about it with rigor! But, no. There are things that just have to be learned the hard way on the floor rather than by memorizing notation/images from a book. Dancing cannot be learned only from analysis. Professional dancers might be able to learn new dances quickly from notation, but let's not kid ourselves: professionals would have to spend some time recreating a dance on the floor, they would bring a great deal of experience that makes that task easier, and they wouldn't end up recreating the original quite the way its long-ago practitioners would see as equal. Amateurs would need quite a bit more time and guidance to recreate a dance well from notation.
