We have come a long ways. From just jiggling to a beat. 8000 years ago, to the dancing we do today. Somewhere along the line all over the earth, these savages learn to accent one count and the other was less. The Two Count measure. Then some dummies went more and developed the three count, accenting the one. Some may have gone to six counts but that is hazy. And they could go forward, walking, or backward or sideways. They could even turn to the left or right. So when music began they could have a little more fun moving to the music in many ways.
