The German composer Carl Maria von Weber is best known for his operas, of which he wrote 10 between 1798 and 1826. His first four exist in various states: Die Macht der Liebe und des Weins (composed 1798) is completely lost; two fragments survive for Das Waldmädchen (1800); the libretto to Peter Schmoll und seine Nachbarn (1803) is lost; and only three numbers from Rübezahl (composed 1804–05) survive. Weber's mature operas—Silvana (1810), Abu Hassan (1811), Der Freischütz (1821), Die drei Pintos (composed 1820–21), Euryanthe (1823), Oberon (1826)—all survive intact; they were all performed within his lifetime, except Die drei Pintos which was posthumously completed by Gustav Mahler. After his family moved to Munich in 1798, the 13-year-old Weber began study with Johann Nepomuk Kalcher, under whose supervision he wrote his first opera, the Singspiel Die Macht der Liebe und des Weins; the work was never performed. Weber's first operatic success came with Silvana, on a libretto by Franz Carl Hiemer that was reworked from Steinsberg's earlier one to Das Waldmädchen. (Full list...)
