Answer:
Modern dance is an American contribution to choreography, much as jazz is a product of American culture. Pioneers in modern dance were and are bold, experimental, initially shocking and obsessively concerned with exploring the language of the body and all its possibilities. Martha Graham, Ruth St, Denis, Isadora Duncan, Merce Cunningham, Paul Taylor, Alvin Ailey and more incorporated ballet, jazz, ethnic dance and a unique series of moves that are more than steps—but as clearly defined and as challenging to master.
