Modern dance is a style of western concert dance which began loosely in the late 19th century and early 20th-century. Modern dance, which has birthplaces in the United States as well as Germany, was a direct response to ballet as the primary form of concert dance. Modern dance refused aspects of classical ballet and broke away from codified movements and balletic narrative structures. Because of early pioneers like Martha Graham, modern dance now encompasses a wide range of styles, many of which are associated with renowned schools and masters. Eventually, postmodern dance would reject the formalism of modern dance and include elements such as performance art, contact improvisation, floor work, release-technique, and improvisation.
