Clearly. Actually, it's very very easy to tell which movement is based around a pivot. Because there's a pivot in the movement. Funny that. As an exercise, I'll let you guess how to tell that a movement is based around a step. Thanks for the lesson. The pivot is one key element - and again you seem to be willfully missing the entire concept of the words "based around". You also seem to be ignoring my other 2 criteria for differentiation - the music and the embrace. But if you seriously believe that people pivot as much in close embrace, to traditional music, as they do in open embrace to non-traditional music (and vice versa), then we'll just have to agree to disagree. My personal definition works for me. It seems clear, objective and measurable. But it's my personal definition. I was asked how I defined it, and I replied.
