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.
Aida Aida (] ) is an opera in four acts by Giuseppe Verdi to an Italian libretto by Antonio Ghislanzoni. Set in Egypt, it was commissioned by and first performed at Cairo's Khedivial Opera House on 24 December 1871; Giovanni Bottesini conducted after Verdi himself withdrew. Today the work holds a central place in the operatic canon, receiving performances every year around the world; at New York's Metropolitan Opera alone, "Aida" has been sung more than 1,100 times since 1886. Ghislanzoni's scheme follows a scenario often attributed to the French Egyptologist Auguste Mariette, but Verdi biographer Mary Jane Phillips-Matz argues that the source is actually Temistocle Solera.
