The first night of Tammy Burstein’s “Rhythms in Waves” 5Rhythms workshop at the Paul Taylor Studio on the Lower East Side followed an extremely unpleasant day in my own small life. I stepped into the high-ceilinged rectangular room, with its clean, metal theatrical fixtures and foot-scuffed black floor and immediately collapsed, touching my forehead to the floor, grateful to enter the charged space of dance, and looking forward to three consecutive days of intentional moving—hoping it would provide me with some kind of antidote.
