Between Pelléas et Mélisande and Riders to the Sea, which one has more acts?
Riders to the Sea (opera) Riders to the Sea is a short one-act opera by Ralph Vaughan Williams, based on the play of the same name by John Millington Synge. The composer completed the score in 1927, but it was not premiered until 1 December 1937, at the Royal College of Music, London. The opera remained largely the province of students and amateurs until it entered the repertoire of Sadler's Wells in 1953.
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".
