Ballet is a type of performance dance that originated during the Italian Renaissance in the 15th century and later developed into a concert dance form in France and Russia. It has since become a widespread, highly technical form of dance with its own vocabulary based on French terminology. It has been globally influential and has defined the foundational techniques used in many other dance genres/cultures. Ballet has been taught in various schools around the world, which have historically incorporated their own cultures to evolve the art. See glossary of ballet.
A ballet, a work, consists of the choreography and music for a ballet production. A well-known example of this is The Nutcracker, a two-act ballet originally choreographed by Marius Petipa and Lev Ivanov with a music score by Pyotr Ilyich Tchaikovsky. Ballets are choreographed and performed by trained ballet dancers.
