Nevertheless, if you regard a grand circle as a rectangle instead of as a
circle (while being danced -- yes, I know it begins and ends as a square),
then, there is a problem of speeding upand slowing down. If it's a
circle, there is not. >>

hi priscilla --

you are right. the 1M to 1W distance is nominally 6' and the 1M to 2M is 3'
and another 3' to 3M. i said 3-4' just to allow a little leeway for the set
to elongate, as they often do. i was referring to the 1M-2M distance, not
the overall length of the set, which is twice that.

if we go with the 6x6 dimensions, and use the 1-1-2 phrasing, then 1M will
cross the set in 1 bar (6'); advance to 2W position in 1 bar (3', or half the
speed); then on to 3W position in 2 bars (again 3', but at 1/4 the speed of
his initial crossing.) that's where the factor of four comes from.

NOW, before anyone jumps on me, i realize that this strict interpretation of
time and distance is overly rigid, and that in practice, things even out a
lot. But that is not obvious to beginners, and they have a better shot at
doing it smoothly if they have an intellectual understanding of the need to
change their forward speed.

as far as considering it a circle goes (rather than a rectangle), if we
suppose that the corners of the 6'x6' square set become 4 points on a circle,
then the distances become the arcs of the circle, and there are 360/4 =90
degrees from one "corner" to another. Then there is still a factor of four
in speed, because 1M starts by covering 90 degrees in 1 bar; continues on the
next 45 degrees in 1 bar; and then does 45 degrees in 2 bars. when you say
there is no change in speed if you do it in a circle, you must be envisioning
a very large amount of "smoothing", which is certainly easier to do in a
circle than a rectangle.

Experienced dancers, like yourself, may achieve this smoothing so intuitively
that they don't realize it's happening, but the (admittedly) overly-strict
interpretation of the time and distance is still inescapable.

I think.

cece
