16: A GENERAL-PURPOSE VERB - CIRCULATE
Circulate is an action that can take several forms, but they all share the same basic idea.The idea of Circulate is that a group of dancers who are arranged along a path will each move forward one position along that path. For example, in a box, there are four positions, and there is a natural path that goes through all four positions.
Some people find it helpful to think of this path as being like a railroad, with the positions corresponding to stations, and the dancers corresponding to trains. As with a train on a railroad track, the dancers can only move along the path. The path itself may be curved, but the dancers must stay on the path, and they can only go forward or back along the path. They can't move "sideways", off the path.
For a particular path, each dancer has only one possible "next position" -- the next one along the path in the direction that he or she is facing. Also note that since the path is closed, connecting back on itself, if a dancer circulates enough times (in this example, four times), that dancer will arrive back at his/her original position.
