The dance path is matched by the music bar lines.
To show retracing of the path, the path is shifted
right (shown with a dashed line). In the more complicated
path to the right, a dancer traces four circles (of the
same diameter), but each repeat of a circle is connected
with dotted lines to allow different steps, arm movements,
etc. on each traversal of a circle. Multiple dancers each
following their paths. (See Wendy Hilton, pp. 91, 94, 95)
