Le Conservatoire, or A Marriage by Advertisement (Konservatoriet eller et Avisfrieri) is a two-act vaudeville ballet created by the Danish choreographer and ballet master August Bournonville in 1849 for the Royal Danish Ballet. The ballet's setting is a dance studio at the Conservatoire de Paris. Bournonville studied at the Paris Conservatoire in the 1820s with the renowned dancer Auguste Vestris. The ballet launched the career of prima ballerina Juliette Price. A divertissement within the larger work called "The Dancing School" (Pas d'école) permitted Bournonville to display the basics of his style and raise them to the level of enduring art.
