Could a down swing generate between 3 to 1 ( beat ). Such as natural turn in waltz , preparatory step on three , there is a down when I rotated my joints of right lower limb and pressed my right ankle on 3...then my weight transfered to my left foot on 1. I feel lack of sense swinging or down swing at all . Does it only appear in some particular steps occupying 2 or 3 beats ? Sorry, I always ask silly questions because of that I knew little about dance.

Yichen. I think a good look at the technique book will answere most of your problems. For instance. In the Waltz as in other dances there is no foot rise on the back half of any turn or Closed Change when danced backward. Otherwise for the Man, commence to rise at the end of 1.Continue to rise on 2 and 3. Lower at the end of 3. Then commence to rise at the end of 4 ( No foot rise ) Continue to rise on 5 and 6. Lower at the end of 6. The term No Foot Rise clearly means that the left heel is kept in contact with the floor until the right foot is in position. That also includes the ladies weight. It should still be on step 1 untill step 2 is in place. Then just follow the man up. When reading from the book you would be well advised to read all of the front pages which is called the Introductory Section. Try to remember that in Modern Ballroom the lady is a Ghost in a Dress.

I think you should read the tec book yourself before you start to give advice.

If you're going to object, the least you can do is to name a figure that does feature foot rise in this situation. And let's clarify the situation to what was clearly intended: any backwards step 1 - can you find one that has foot rise?
