That the entire idea of dancing is for the audience to see the moves, but with Beriozka things are a little bit different. In this traditional Russian dance, performers appear to be floating across the stage, and it is nothing short of impressive. Their secret technique is called the floating step and in a second you are going to have a hard time trusting your eyes!
I thought that these dancers are standing still while the stage beneath them seems to be moving. Even the skirts doesn’t seem to ruffle, but that is all part of the show. The women actually have to stay on their tippy toes (en pointe) the entire time to maintain the illusion.
