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.
Khovanshchina Khovanshchina (Russian: Хованщина , "Hovánščina", sometimes rendered The Khovansky Affair; since the ending -ščina is pejorative) is an opera (subtitled a 'national music drama') in five acts by Modest Mussorgsky. The work was written between 1872 and 1880 in St. Petersburg, Russia. The composer wrote the libretto based on historical sources. The opera was unfinished and unperformed when the composer died in 1881.
