The Country Triple is also called the Triple Two-Step, the Shuffle, or the Fort Worth Shuffle. The footwork timing is often called out as triple step, triple step, walk, walk. It is often called “swing on the move,” since the dance uses a progressive version of the triple timing swing basic. Like the polka and like the standard two step, the triple two-step progresses around the perimeter of the dance floor in a counterclockwise fashion.
