There used to be a strong community tradition about the flow of waltzing at contra dances. It was fast around the outside and stationary in the middle. You could do a nice Viennese, flying around the outside of the hall with no trouble, except in the most crowded of halls. You could do tricks galore standing virtually still. You could do everything in between. There were a lot fewer collisions, despite some much-faster-moving dancers. Halls were at least as crowded as they are today.
Today, that's a near-impossibility in many halls. There tends to be a slow-circulating middle, but there isn't the former gradient of speeds outside of that zone that increases options while reducing collisions. It's all just a slow-moving mass, and people are so focused on their partners that collisions are common.
I think everyone's enjoyment would increase if we followed four simple considerations:
a) If someone passes you on the inside, you are a slower-circulating couple and should move closer to the middle,
b) If you pass someone on the inside, you are a faster-circulating couple and should move farther out,
c) Moving counter-flow or wagging strongly sideways (much more than just a side-by-side promenade) in the traveling ring are no-nos,
d) Both partners really need to look out for others all the time and protect each other from collisions, elbows to the face, etc. This is not just the lead's job, especially if they're being considerate and moving backward for a substantial portion of the time.
I hope this is on-topic for this group. Callers are the evening's
MCs, but they usually don't have much to do with waltzes, other than to
announce them. However, what I'm talking about here would probably
come about if callers a) announce it and b) include it in their
waltz lesson, if they hold one. And maybe c) discuss it with dancers
and organizers.
Happy(ier) waltzing!
