Ballet dance is a very formal and strict type of performance dance. Ballet is a formalized form of dance with its origins in the Italian Renaissance courts of the 15th and 16th centuries. Ballet spread from Italy to France with the help of Catherine de’ Medici, where ballet developed even further under her aristocratic influence. Early ballet dance performances were presented in large chambers with most of the audience seated on tiers on three sides of the dance floor.Early ballet dancers were not as highly skilled as they are now, as ballet dance has become a highly technical form of dance with its very own French vocabulary. Ballet dance is typically performed to classical music. It is taught in ballet dance schools and studios around the world, with students ranging in age from toddlers to adults. In order to become proficient at ballet dance, one must be extremely dedicated to the art and diligent in regards to practice and rehearsal time.
