THE SCIENCE OF DANCE

Are you familiar with the scene of the movie White Nights in which the protagonist bets on 11 pirouettes to win 11 rubles?

I’m sure dance fans know it by heart. One of the greatest dancers of all time, Mikhail Baryshnikov, is involved in this enterprise.

Explanations for its impeccable performance are found in the biomechanics of dance.

Yes, there is a science that outlines the very precise rules that govern each dance movement.

It is defined as "the science which examines the internal and external forces acting upon a particular dancer and the mechanical and physiological effects produced by them".

In particular, the turns will be beautiful if the angular impulse that determines the circular movement of the body is almost equal in intensity and direction to that needed to perform the desired number of turns in the desired position and in the set time.

Every body part helps to achieve success:

- The head gives the main shot. It is necessary to fix a precise point to help maintain balance.

- The arms contribute to the stability of the movement and assume a key function depending on the type of turn.

If the dancer rotates on himself by turning on one foot and holding the other leg raised (pirouette), the arms must keep the same position so as not to vary the moment of inertia, while in some figures the arms draw the trajectory of the movement.

The spectacularity of well performed dance steps is based on the laws of physics.
