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.
The Golden Cockerel The Golden Cockerel (Russian: Золотой петушок , "Zolotoy petushok") is an opera in three acts, with short prologue and even shorter epilogue, by Nikolai Rimsky-Korsakov. Its libretto, by Vladimir Belsky, derives from Alexander Pushkin's 1834 poem "The Tale of the Golden Cockerel", which in turn is based on two chapters of "Tales of the Alhambra" by Washington Irving. The opera was completed in 1907 and premiered in 1909 in Moscow, after the composer's death. Outside Russia it has often been performed in French as "Le coq d'or".
