Most of us fall far short in understanding ballet let alone Chinese Dance. This item elucidates both through the act of comparison. It is remarkable to see two completely different traditions side by side using mostly the same tools.
We need to see more of that in other arts as well. In fact we need to make a discipline out of comparing arts, rather than the arts themselves. For instance, i am interested in the Olmec paint stroke which informed their glyphs.
Without the art of comparison new forms are first shocking or obviously novel. Yet logically consistent once past that..
