Box Step is a basic dance step named after the pattern it creates on the floor, which is that of a square or box. It is used in a number of American Style ballroom dances: Rumba, Waltz, bronze-level Foxtrot. While it can performed individually, it is usually done with a partner. This is the most common dance step in the Waltz. In International Standard a there is a similar step called Closed Change.
A typical example, the leader begins with the left foot and proceeds as follows.
Every step is with full weight transfer. During the second and fourth step it is advised for the foot to travel along two sides of the box, rather than along its diagonal.
Rhythm varies. E.g., it is "1-2-3,4-5-6" in Waltz and "Sqq, Sqq" in Rumba.
In other dances (and in variations) the box may start from any foot, either back or forward, even sidewise. For example in the Quadrado figure of Samba de Gafieira the leader steps (starting with the left foot) "left-together-back, right-together-forward".
To do the Box Step for the Waltz, partners should start in the closed position. Usually the man will lead and the woman will follow.
The pair should end up where they began, and can start all over again. Emphasis should be made on sliding the foot rather than making a forced, heavy step.
