Ballet is a type of performance dance, that originated in the Italian Renaissance courts of the 15th century, and which was further developed in France and Russia as a concert dance form. The early portions preceded the invention of the proscenium stage and were presented in large chambers with most of the audience seated on tiers or galleries on three sides of the dance floor. It has since become a highly technical form of dance with its own vocabulary. It is primarily performed with the accompaniment of classical music and has been influential as a form of dance globally.
