Which opera has more acts, Genoveva or Moses und Aron?
Moses und Aron Moses und Aron (English: "Moses and Aaron") is a three-act opera by Arnold Schoenberg with the third act unfinished. The German libretto is by the composer after the Book of Exodus. Hungarian composer Zoltán Kocsis completed the last act, with Schoenberg's heirs' permission, in 2010, but as of 2014 "Moses und Aron" was almost always performed as Schoenberg left it in 1932, with only two of the planned three acts completed.
Sieg der Schönheit Gensericus oder Sieg der Schönheit TVWV 21:10 (Hamburg 1722 and Braunschweig) is a comic German-language opera in three acts by Georg Philipp Telemann. It was performed at the Oper am Gänsemarkt, while Keiser was director. Unlike "Orpheus" and "Flavius Bertaridus", the opera contains no Italian-language set piece arias. The librettist was Christian Heinrich Postel.
