Her search for a natural movement form sent her to nature. She believed movement should be as natural as the swaying of the trees and the rolling waves of the sea, and should be in harmony with the movement of the Earth. Her great contributions are in three areas.
First, she began the expansion of the kinds of movement that could be used in dance. Before Duncan danced, ballet was the only type of dance performed in concert. In the ballet the feet and legs were emphasized, with virtuosity shown by complex, codified positions and movements. Duncan performed dance by using all her body in the freest possible way. Her dance stemmed from her soul and spirit. She was one of the pioneers who broke tradition so others might be able to develop the art.
Her second contribution lies in dance costume. She rejected ballet shoes and stiff costumes. These were replaced with flowing Grecian tunes, bare feet, and unbound hair. She believed in the natural body being allowed to move freely, and her dress displayed this ideal.
Her third contribution was in the use of music. In her performances she used the symphonies of great masters including Beethoven and Wagner, which was not the usual custom.
She was as exciting and eccentric in her personal life as in her dance.
