I just retraced some rather faded handwriting on the white board. To do so, I had to entrain my movement (and all is movement, when we look at it), to a past series, as I thought those thoughts and wrote them on the board.
This is just like synchronous speech, where two people try to match their motor control. Remember, all we see is that brains move muscles. So when we ask about shared experience, that must mean shared movement. Is movement all muscle? Is it just shared dynamic?
Can you find a few people to do exercises in shared movement with? It’s not quite dance, but it is also. But its not about expression, but resonance. Neither alone nor together, but resonance.
