I have a question about the lady's poise or position when dancing outside partner (e.g. step 4 in a weave).
If the lady is in good position for dancing in normal closed hold, how can she maintain this when dancing outside partner, where clearly the separation of the hips must be greater (even with CBM). Won't this give the lady the wrong shaping? If not, how is this wrong shaping avoided?

"If the lady is in good position for dancing in normal closed hold, how can she maintain this when dancing outside partner, where clearly the separation of the hips must be greater (even with CBM)."

The answer is that the seperation of the hips should not be greater - at least not the side-to-side seperation.

Outside partner is a direction of movement relative your your body alignment, and it is a stretch within your body - but it is not a seperation from your partner.

It's easiest to learn for a lowered action like at the end of a lock step (lady backwards). Stand sort of as if you were shooting a bow and arrow - left foot forward, right back, right knee bent diagonally forward and left, left shoulder forward and left, right hip pulled back and creased. Stretch into that position and take the backwards step in CBMP with the left. Or take a fowards step in CBMP with the right - it's basically the same.

Then learn to do the same thing on the ball of the foot at weave height. Or substantially more difficult, rolling through the foot over an extended leg, such as in the feather.

Hi anonymous.
On step 4 in a weave, my step (man) is left foot back with CBM. Lady's step is right foot forward outside me (with CBM)
If our hip separation is no more than in normal hold, where does the lady's right foot go? My right side is blocking it. Most dancers i see (some are very good dancers) handle this by the lady opening her hips a little so there is space to bring her left leg outside the man. Coming out in promenade gives a similar (at least closely related) problem, but at least the technique book 'allows' for the lady to open her body and hips to cope with it in this case.
When i watch our dancing this weave 4th step on video there is an element of my partner leaning a little to her right, which i would like to eliminate. But i can't see how to do it.
