The oversway is something of an opposite to the promenade sway.
We step side on the lead, but we soften that knee instead of stretching
up, and the man stretches the left side instead of the right, thus
closing the woman's head and moving to a closed position, rather than
semi-closed. The figure is finished with a little left face body
You can perform the oversway by itself, but
more often, you will be asked to do a promenade sway and then to change
to an oversway, or simply "change the sway."
promenade sway is a left sway down line. Changing from right-side
stretch to left-side stretch changes the left sway to right sway and
the semi-closed position to closed position. Again, a little seasoning
is added to the dish in the left- face body rotation and extension of
the upper body.
