The directions where dancing is taking place are
numbered. Assuming that the dancing is on a "stage"
in a theatre, then the orientations are as follows
(see figure "a"):
Figure "a", position "0": the audience.
Figure "a", position "1": right front corner of the "stage".
Figure "a", position "2": right side of the "stage".
Figure "a", position "3": right rear corner of the "stage".
Figure "a", position "4": back of the "stage".
Figure "a", position "5": left rear corner of the "stage".
Figure "a", position "6": left side of the "stage".
Figure "a", position "7": left front corner of the "stage".
Figure "c": When turning for example, the direction,
is it turning left or right? A "+" means turning right,
a "-" means turning left. Thus "c" shows that starting
facing direction "1", turn right from direction "1",
progressively to direction "7", then to direction "0"
(facing the audience), then turn left from direction
"0", progressively to direction "2".
