Modern dance is a more relaxed, free style of dance in which choreographers use emotions and moods to design their own steps, in contrast to ballet’s structured code of steps. It has a deliberate use of gravity. Because of the common history, the two forms (classical ballet and modern) share a similar terminology and structure. Modern dance is a term that applies to a variety of different disciplines, all with subtly different techniques that responded to the imperialism of ballet through varying, culturally specific catalytic factors.
