Mathematicians and scientists often employ simplified, idealized models of the real world as a way to understand complex concepts, processes, and systems.
As I was awakening this morning I thought again about the question you raised at the practica, of how to lead a leg wrap to the closed side.
(You were already in good shape with leg wraps to the open side, both in parallel and promenade positions. Many things come easier on the open side where there is more room to maneuver.)
A mental model for the follower’s axis came to my mind, and it seemed useful. See if you find it any help. Take a piece of string of, oh, say about 12 inches. Put a simple overhand knot at each end and fasten a binder clip over each knot. Now hold the string in the middle, with the binder clips dangling down.
Where you are holding the string in the middle represents the follower’s pelvis, and the binder clips represent their feet and leg weight.
If you hold one “foot” in place, representing the follower’s standing leg, and then raise the “pelvis” directly over it, you’ll see that the free leg collects to the standing leg. If you “pivot” the follower on their own axis (by twirling thumb and finger) the legs and feet stay collected.
But now, while still holding the standing foot in place, moving the pelvis to the side and forward toward you, you see that the free leg swings away from the standing leg. And if someone else’s standing leg – yours! – is in the way, the swinging leg will wrap around it.
Now here is a detail that gets glossed over during some instruction. The leader may have to make one or more small adjustments to the position of their own feet during the move in order to gain a position that will allow the tilting of the follower’s axis. A tiny side step right – as you pivot the follower in a back boleo about their axis – gives you position for the second part of the movement, to bring their axis to the side, opening the legs. Then as you “swing” them forward and around YOUR axis a tiny back step on the left tilts their axis forward. It’s a miniature volcada.
Two additional points. When you start the follower’s back rotation for the boleo you are rotating YOUR torso about THEIR axis – keeping their axis vertical. Then in the next part where you swing forward you are rotating YOUR torso about YOUR standing leg, the left back one. This leads the follower’s torso to rotate about your axis. The second point is that it helps to create a spiral, going from a lower elevation in the boleo to a raised torso at the height of the leg wrap, to give the follower the idea of lifting the leg as it wraps.
But two actions by the follower can thwart all of this. If they, consciously or not, resist the movement by breaking at the hips, allowing the hips to come forward while the upper body stays back, it causes two problems. First, the leader’s movements can’t be transmitted from the torso down to the legs because it gets lost at the hips, and second, it causes the follower’s axis to tilt down toward the floor, having the effect of making them heavier, instead of forward to the leader. Also, if the follower can’t give up control of their free leg, allowing it to swing freely, but instead holds tension, such as bending the knee or keeping it collected, then the leg won’t swing away from the follower’s body regardless of how well it’s led.
There is a big element of trust involved. Any time the leader tilts the follower off axis, the follower must feel that they are secure and safe in committing to this leader. Likewise, with a follower’s leg wrapping around the leader, or with either partner’s leg intruding into the space between one’s legs, they must feel that they are being treated respectfully.
