Between Pelléas et Mélisande and Riders to the Sea, which one has more acts?
Pelléas et Mélisande (opera) Pelléas et Mélisande ("Pelléas and Mélisande") is an opera in five acts with music by Claude Debussy. The French libretto was adapted from Maurice Maeterlinck's Symbolist play "Pelléas et Mélisande". It premiered at the Opéra-Comique in Paris on 30 April 1902 with Jean Périer as Pelléas and Mary Garden as Mélisande in a performance conducted by André Messager, who was instrumental in getting the Opéra-Comique to stage the work. The only opera Debussy ever completed, it is considered a landmark in 20th-century music.
La journée aux aventures La journée aux aventures ("The Day of Adventures") is an opera by the French composer Étienne Méhul. It takes the form of an "opéra comique" in three acts. It was first performed at the Opéra-Comique, Paris on 16 November 1816. The libretto is by Pierre-David-Augustin Chapelle and Louis Mezières-Miot. This was the last of the composer's works to be premiered in his lifetime and was a great success; it enjoyed 66 performances before the end of 1817 and helped remedy the financial problems of the Opéra-Comique. It was revived to acclaim in a German translation in Berlin in December 1839.
