BALLET is a formalized type of performative dance, started in sixteenth and seventeenth century French courts, and which was further developed in England, Italy, and Russia as a concert dance form. The early ballet dancers were not as highly skilled as they are now. It has since become a highly technical form of dance with its own vocabulary. It is mainly performed with the accompaniment of classical music. It has been influential as a form of dance globally and is taught in ballet schools around the world, which use their own cultures and societies to inform the art. Ballet dance works (ballets) are choreographed, and also include mime, acting, and are set to music (usually orchestral but occasionally vocal). Ballet dancers are required to wear proper attire: black or solid color leotards with pink tights and ballet slippers or pointe shoes. Hair must be in a bun preferably or pulled back from face.
