Which of the operas "Elektra" and "Vanessa" had more acts?
Elektra (opera) Elektra, Op. 58, is a one-act opera by Richard Strauss, to a German-language libretto by Hugo von Hofmannsthal, which he adapted from his 1903 drama "Elektra". The opera was the first of many collaborations between Strauss and Hofmannsthal. It was first performed at the Dresden State Opera on 25 January 1909. It was dedicated to his friends Natalie and Willy Levin.
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.
