French composer Jacques Offenbach's operetta Orpheus in the Underworld, featuring the music most associated with the can-can (audio featured), was first performed at the Théâtre des Bouffes-Parisiens in Paris.

Jacques Offenbach was a German-born French composer, cellist and impresario. He is remembered for his nearly 100 operettas of the 1850s to the 1870s, and his uncompleted opera The Tales of Hoffmann. He was a powerful influence on later composers of the operetta genre, particularly Franz von Suppé, Johann Strauss II and Arthur Sullivan. His best-known works were continually revived during the 20th century, and many of his operettas continue to be staged in the 21st. The Tales of Hoffmann remains part of the standard opera repertory.

Operetta is a form of theatre and a genre of light opera. It includes spoken dialogue, songs and including dances. It is lighter than opera in terms of its music, orchestral size, and length of the work. Apart from its shorter length, the operetta is usually of a light and amusing character. The subject matter may portray "lovers' spats, mistaken identities, sudden reversals of fortune, and glittering parties". It sometimes also includes satirical commentaries.

Orpheus in the Underworld and Orpheus in Hell are English names for Orphée aux enfers, a comic opera with music by Jacques Offenbach and words by Hector Crémieux and Ludovic Halévy. It was first performed as a two-act "opéra bouffon" at the Théâtre des Bouffes-Parisiens, Paris, on 21 October 1858, and was extensively revised and expanded in a four-act "opéra féerie" version, presented at the Théâtre de la Gaîté, Paris, on 7 February 1874.

The can-can is a high-energy, physically demanding dance that became a popular music-hall dance in the 1840s, continuing in popularity in French cabaret to this day. Originally danced by couples, it is now traditionally associated with a chorus line of female dancers. The main features of the dance are the vigorous manipulation of skirts and petticoats, along with high kicks, splits, and cartwheels.
