Jazz dance is a term used to describe the performance dance technique and style that emerged in America in the early twentieth century. Jazz dance began as an African American social dance that had roots in African slave dances. Over time, a clearly defined jazz genre emerged, changing from a street dance to a theatrical dance performed on stage due to the work by artists such as Jack Cole (choreographer), Bob Fosse, Eugene Louis Faccuito and Gus Giordano. Today’s Jazz Dance as a discipline may be danced using many different styles and tempos, using themes based on Afro-Cuban, Oriental, Spanish or other national themes. It may be performed as a character but it may also be abstract in nature. Show Dance in the broadest sense is based either on any Jazz/Lyrical, Ballet and/or Modern and Contemporary dance technique. It is very important to present harmony of idea, music, dance, choreography, costume and props in the presentation, and all Show Dance presentations are be based on a concept, story, theme or idea.
