Hi All,
There is a basic figure in the Quickstep called the Natural Pivot Turn. This is a composite figure made up of 1-3 of the Natural Turn and a Natural Pivot. A figure of 4 steps. The Natural Spin Turn is also a composite figure of 6 steps consisting of 1-3 Nat. Turn; step 4 a Nat. Pivot; steps 5 and 6 a Nat. Spin. You can see that a Pivot is one step and a Spin is two steps. Whether the figure is wrongly named is debatable. Yet we have the Double Reverse Spin. Is this wrongly named? We don't have to dance it twice! Any comments?

I have the history of ballrom dancing.
The Double Revers Spin was intoduce by a Maxwell Stewert in 1922. They were always danced as a double, hence the name. That was the same year that the cross behind in the Foxtrot was substited by the Feather Step. Spinning, and Pivoting. One is centripetal,inner force, the other centrifugal, outer force. There are some wonderful instruction by John Woods and Anne Lewis on this very subject in their video tape.
