We should look deeper into the Technique currently being used by our peers in the Modern Waltz. A Closed Change, commonly called a Change Step.
In between each step there is a space, just as there is between each beat. This space must be used. Which makes the count 1 and 2 and 3 and. You will notice that the foot closes on 2 and. Feet together on 3, at which point we are at our highest. We then lower on the count of and. We are now at our lowest. There is no more lowering only the natural loss of height when we drive on beat 1.
