Am frequently told by my teacher that it is all an illusion, hence you should never try to copy what you see!!!!!
Once you learn that foot position etc are a consequence of body rotation/moving centre etc life suddenly becomes much easier and faster (may be this should be in the wish you had been told earlier thread.)
(I hope I got it right - still learning, can't create an illusion but fun trying!!!)
You are absolutely correct, but missing one important point. ED answers this in the post....
some foot positions precede the step - as far as I know that is the only way to avoid pivots in tango - turn the foot in the direction of the next step as you place it on the floor - then you will not have to pivot on it and you get a much more grounded look
This is very much corrrect. Your missing element... in the swing dances (waltz, fox, etc).
