Hi Seth and Luke, This discussion has inspired me to revisit grid contras. We danced a grid contra yesterday at our monthly dance in Christchurch. The majority of the dancers (24) were experienced but 8 were less so. Even so it went well and all found it fun. Here is a video of the setting up, teaching, walk throughs and the dance. With a bit of computer animation thrown in. https://youtu.be/gLKBm4j7gbQ There were a few hiccups with the filming as my camera suffered tripod droop! I had a great birds eye view from the stage, but the camera less so :-( I called a variation of Petronella Fancy which I wrote in 2012. It was inspired by Kim's Game by Colin Hume. Petronella Fancy was originally a type of 4 face 4, but easily extended to an arbitrary regular grid. The variation I used last night changed the order (to suit the music better) and used both a double progression and double transgression. We danced on a grid of 4 adjacent contra lines of length 4 couples. Total of 32 dancers. The dance has a period of 10 during which each dancer will swing 5 different neighbors (each twice). The 2s in the left line, 1s in the right line, 2s in front hands-four and 1s in back hands-four all travel around the perimeter of the grid. The 6 remaining couples form 3 pairs that vibrate back and forth. This is the version we danced. Petronella Fancy DP A1 (4) [Entire oval along the set] Balance ring (4) Petronella turn (4) [Entire oval along the set] Balance ring (4) Petronella turn A2 (4) Pass through along (NR) (4) Pass through along (N2R) (8) N2 neighbor swing; face partner B1 (8) Men allemande left 1 & 1/2 (8) Partner swing B2 (8) [Groups of four] Circle left 3/4 [with N2]; face along (8) Lines across the set forward and back In general this dance is interesting if the grid does not have many interior hands-four rings, as those couples vibrate and see very few neighbors. Here is the original http://www.ibiblio.org/contradance/thecallersbox/dance.php?id=12042 It had a single progression and this means that couples traveling around the perimeter are out very frequently which is not much fun. I can easily generate animations for other size grids if anyone is interested. Cheers, Bill On 10/10/2018 9:05 a.m., Tepfer, Seth via Callers wrote:
