I often teach ballet over Zoom in the evenings, shortly after sunset. Without the natural light coming from my living room window, I drag a table lamp next to my portable barre so that the computer's camera can see me clearly enough. I prop the laptop on a chair taken from the kitchen and then spend the next few hours running back and forth between the computer screen of Zoom tiles and my makeshift dance floor.
Much of this setup is the result of my attempts to recreate the most important aspects of an in-person dance studio: I have a barre, a floor and as much space as I can reasonably give myself within a small apartment. I do not, however, have a mirror, and neither do most of my students.
