Choreography, for all intents and purposes, is the art of motion. Animation is all about choreography, as animation is all about motion. Virtually any living thing is defined in a large part by its motion. Think of how an elephant moves, and compare that to a dancer. Immediately, you can tell which is which, and this “simple truth” is something that every animator strives for.
As you might expect, this is an extremely large subject, with millions of different points of view, far beyond the scope we have here for any legitimate discussion. Start by Googling “Choreography.” Enjoy.
