"if we had more time we'd throw in a square"
The contra dance medley at
NEFFA is normally six dances,
each six times through (well, the last one is five or seven).
I was thinking about what you'd need to do if you actually
wanted to include a square...
The main problem is that you need to switch the dancers
from groups of four to groups of eight, and there isn't really
a great way to do this. In computer science speak the issue
is that it takes time linear in the number of dancers. But
maybe you could have the top couple sashay down from the top,
and everyone takes hands eight as they pass, which is fast
enough even in a long hall that it's ok (~16 beats, and you
adjust the time by figuring out how much intro to do on the
square)? And then tell anyone left out at the bottom to
square up?
(Going back into contra lines from aligned squares should
be easier: side couples circle left three quarters and twirl
to swap, lines at the sides, etc)
Would this work?
