I teach aerial silks at the Pittsburgh Dance Center. Every week I have a handful of classes, taught on two rows of silks with about a dozen dancers. Some times the efforts are organized and coordinated, for example when we all gather to work on a new movement or trick. Some times it is a wild free for all with people climbing up down the silks at their own pace, moving through small routines or figuring out new moves for themselves. Each individual class has its own pace, its own story, that is often missed because the focus is on participation and there is rarely anyone other than me in a position to observe.
