Modern dance is a dance school that rose in the west in the early 20th century, as opposed to classical ballet. Its main aesthetic point of view is to oppose the formalism tendency of classical ballet, which is conformist and divorced from the phenomenon-single life and pure pursuit of skills. It advocates getting rid of the rigid movement procedure of classical ballet, freely expressing people's true feelings with dance movements that conform to the laws of natural movement, and emphasizes that dance art should reflect modern social life.
Its most striking feature is that it reflects the social contradictions in modern western countries and people's psychological characteristics, so it is called modern dance. Helen Tominis, an American modernist dancer, summed up the difference of modern dance in this way: "There is no universal law, and every artist is creating his own code."
