Classical ballet is any of the traditional, formal styles of ballet that exclusively employ classical ballet technique. It is known for its aesthetics and rigorous technique, its flowing, precise movements, and its ethereal qualities.

Giselle, originally titled Giselle, ou les Wilis, is a romantic ballet in two acts with music by Adolphe Adam. Considered a masterwork in the classical ballet performance canon, it was first performed by the Ballet du Théâtre de l'Académie Royale de Musique at the Salle Le Peletier in Paris on 28 June 1841, with Italian ballerina Carlotta Grisi as Giselle. It was an unqualified triumph. It became hugely popular and was staged at once across Europe, Russia, and the United States.
