Which opera has more acts, Genoveva or Moses und Aron?
Genoveva Genoveva, Op. 81, is an opera in four acts by Robert Schumann in the genre of German Romanticism with a libretto by Robert Reinick and the composer. The only opera Schumann ever wrote, it received its first performance on 25 June 1850 at the Stadttheater in Leipzig, with the composer conducting. It received only three performances during the premiere, and the negative criticism it received in the press played a decisive role in Schumann's decision to not write a second opera.
Eugene Onegin (opera) Eugene Onegin (Russian: Евгений Онегин , "Yevgény Onégin"), Op. 24, is an opera ("lyrical scenes") in 3 acts (7 scenes), composed by Pyotr Ilyich Tchaikovsky. The libretto, organised by the composer himself, very closely follows certain passages in Alexander Pushkin's novel in verse, retaining much of his poetry. Tchaikovsky's friend Konstantin Shilovsky contributed M. Triquet's verses in Act 2, Scene 1, while Tchaikovsky himself arranged the text for Lensky's arioso in Act 1, Scene 1, and almost all of Prince Gremin's aria in Act 3, Scene 1.
