hello all- I'm new here, but this thread caught my eye, because I've noticed this same thing. True story from my just finished school year: I had just taught "TN Waltz" to my 5th graders as part of our study of TN songs. To help the kids understand/ analyze meter, I teach them the basic waltz step. The kids picked up on it quickly, and loved it. To the point that when the principal dropped by one day to observe, this boy-child wanted to show her how to do it. He stood in the middle of the circle of his classmates and danced alone while they sang the song. He was completely at ease, and didn't have a musical background at all!! And this in a rural community where sports, hunting, and fishing are still part of every boy's growing up....it was a moment! I think maybe it's the swaying- like being rocked as a baby.....
