Carl Maria von WeberCarl Maria Friedrich Ernst von Weber (18 or 19 November 17865 June 1826) was a German composer, conductor, virtuoso pianist, guitarist, and critic who was one of the first significant composers of the Romantic era. Best known for his operas, he was a crucial figure in the development of German ''Romantische Oper'' (German Romantic opera).
Throughout his youth, his father, , relentlessly moved the family between Hamburg, Salzburg, Freiberg, Augsburg and Vienna. Consequently he studied with many teachers – his father, Johann Peter Heuschkel, Michael Haydn, Giovanni Valesi, Johann Nepomuk Kalcher and Georg Joseph Vogler – under whose supervision he composed four operas, none of which survive complete. He had a modest output of non-operatic music, which includes two symphonies; a viola concerto; bassoon concerti; piano pieces such as Konzertstück in F minor and ''Invitation to the Dance''; and many pieces that featured the clarinet, usually written for the virtuoso clarinetist Heinrich Baermann. His mature operas—''Silvana'' (1810), ''Abu Hassan'' (1811), ''Der Freischütz'' (1821), ''Die drei Pintos'' ( 1820–21), ''Euryanthe'' (1823), ''Oberon'' (1826)—had a major impact on subsequent German composers including Marschner, Meyerbeer, and Wagner; his compositions for piano influenced those of Chopin and Liszt. His best known work, ''Der Freischütz'', remains among the most significant German operas. Provided by Wikipedia
