Are both Der Freischütz and Der Barbier von Bagdad operas?
Der Barbier von Bagdad Der Barbier von Bagdad ("The Barber of Baghdad") is a comic opera in two acts by Peter Cornelius to a German libretto by the composer, based on "The Tale of the Tailor" and "The Barber’s Stories of his Six Brothers" in "One Thousand and One Nights". The first of three operas by Cornelius, the piece was first performed at the Hoftheater in Weimar on 15 December 1858.
Les brigands Les brigands ("The Bandits") is an opéra bouffe, or operetta, by Jacques Offenbach to a French libretto by Henri Meilhac and Ludovic Halévy. Meilhac and Halévy's libretto lampoons both serious (Schiller's play set to music by Verdi) and light theatre ("Fra Diavolo" and "Les diamants de la couronne" by Auber). The plot is cheerfully amoral in its presentation of theft as a basic principle of society rather than as an aberration. As Falsacappa, the brigand chieftain, notes: "Everybody steals according to their position in society". The piece premiered in Paris in 1869 and has received periodic revivals in France and elsewhere, both in French and in translation.
