Rythm and Texture by Victor Navone

I found this @ Victor Navone's blog, he explains what Texture in animation is...

These are a couple of animation terms that get tossed around a lot, and many animators are not completely clear on exactly what they mean (I wasn't completely sure about them myself until well into my animation career). One reason I think they're so hard to pin down is that there's a lot of overlap (not that kind of overlap) between them, and it's hard to talk about one without referencing the other. Kind of like trying to talk about spacing without talking about timing and arcs. But lest I digress, I'm going to talk a bit about rhythm and texture as specifically as I can, and how important they are in your animation. I suppose I should attempt to define these terms before I go much further, so here's how I understand them:

Rhythm - how the actions or "beats" in a shot are spaced out over the length of a scene. You might also call this "tempo". Unlike with music, good animation has an inconsistent rhythm, making it less predictable.

Texture - the variations of timing and poses in your shot. Big and little actions, slow and fast timing, flurries of action and holds. A shot in which all the actions are the same size, have the same timing, and occur in an even rhythm has no texture.
