Modern dance. The form of dance style known as modern dance is an artistic dance form that allows free movement based on choreography that seeks to provide the audience with a subject and theme. Modern dance performers created this free form style to allow older dancers to continue to dance long after their ballet dance careers ended.
In other styles of dance, the music is a big part of the dance, and the steps are based on the music. The music for Modern and Ballet is mainly used to set the mood of the dance. However, the two styles differ in significant ways. In Ballet, you must follow strict movements that canât be altered much. But Modern dancers break those rules. Modern dance takes a basic movement and adds to it. There are different ways of performing the same step. Ballet steps always are done with turned out feet, unlike Modern, where steps can be done turned out or in parallel.
