Le Conservatoire, or A Marriage by Advertisement
The first act recreates the kind of dance class Bournonville attended at the Paris Conservatoire. In the second, Monsieur Dufour, a Conservatoire inspector, places a matrimonial advertisement but ends up marrying his housekeeper, Mademoiselle Bonjour. The students disguise themselves as attractive women to fool him, with divertissements woven into the action.
