The document discusses the history of ballet dance, beginning with its origins in 15th century Italian Renaissance stage performances incorporating song and costumes. It later evolved in the 1700s under Jean Geogores Noverre to become more dramatic narratives. Today the same traditions and techniques are used, with a typical ballet class consisting of a warmup, center work, exercises at the barre, jumping and turning combinations, and concluding with a reverence. Safety is essential during classes.
