Are both Der Freischütz and Der Barbier von Bagdad operas?
Der Freischütz Der Freischütz , Op. 77, J. 277, (usually translated as "The Marksman" or "The Freeshooter") is a German opera with spoken dialogue in three acts by Carl Maria von Weber with a libretto by Friedrich Kind. It premiered on 18 June 1821 at the Schauspielhaus Berlin. It is considered the first important German Romantic opera, especially in its national identity and stark emotionality.
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.
