I think that Brazilian Jiu-Jitsu needs a shorthand notation of the movements and positions.
Too many times I’ve tried to read text-only blog entries about positions and have had them stop making sense halfway through. For example, people will start talking about an attack from side-mount and then talk about moving your hand to attack, but forget to talk about which hand they mean. The one by their opponent’s head? Or the one by their opponent’s hips?
The thing is, I know I do this, too. I take notes on classes and I know that if I passed them to someone else, they would be lost.
I was asking Susi about how ballet teachers write down their movements they make during a dance, and she told me about dance notation.
So, my proposal is, invent a BJJ shorthand notation. Anyone want to help?
