I found this video on the hardest move of ballet. It says that it involves physics. The hardest move in ballet is 32 pirouettes en pointe. That also includes fouettes. This is seen in Swan Lake and is performed by the Black Swan. The Black Swan must keep her balance while spinning. This video explains how physics help the Black Swan stay on balance.
This was helpful because now I know how the Black Swan manages to stay on balance and how she doesn’t fall. By doing the math I know how to manage to do a fouette like the Black Swan. This is very helpful because it is a visualisation on how to do a proper fouette. In the video they slowed it down and no human can slow down the speed of their turn, because they will lose the momentum and they won’t be able to spin properly. So this video was very useful.
