Tango is based on partners pushing each other, if you exclude this physical interaction you are dancing alone..
I think the reason Peaches and I are arguing with the original statement was because it implied that a follower can't walk backwards while pressing forward unless something pushes her to make her/allow her to move. (and therefore she CAN"T dance alone!)
Every follower who has learned the basic method of walking backwards knows this is false.
On the other hand, you are saying that a follower can't be
LED to walk backwards without being "pushed".
That's not the same thing.
Being able to dance alone is how I know that I can walk backward while pressing forward without a partner to push me. Can I be
led to take a backstep without any pressure (pushing) from my partner at all?
No.
Without a pressure (or movement) to indicate a lead, there IS no lead and therefore I don't move. That's true of EVERY step regardless of lean, style or direction. Yes, you are right that the whole basis is pressure or "pushing" to indicate the next move. Although "moving" might be a better word than pushing.
But that's very different than saying that someone can't walk backwards while pressing forward with their body.
I realize that Andabien's post that started this debate did NOT say "you can't go backwards while pressing forward". It said "you can't walk backwards while LEANING... etc"
I
agreed that if you are leaning (sharing weight to the extent that you would fall over if the other person is removed) you might be able to move your feet back without being "pushed", but obviously your body isn't going to go anywhere without it being moved by or with the other person. Simple physics and geometry say if you're leaning on something, you can move your feet away from it, but if it stays in the same place, so will you.. you'll just be
leaning MORE.
However, not everyone reading these forums has been dancing for awhile... some folks are quite new to tango. I wanted to clarify that
followers still need to learn to maintain forward intention and pressure even when walking backwards, that this IS possible (and it can be practiced alone) and it doesn't require shared weight (leaning) to keep that forward pressure.
I was afraid that Andabien's post might be misleading to newbies which is why I expanded on the thought. It was not a contradiction, it was a clarification for anyone reading who generalized the statement too far.
