Carl Maria von Weber

Carl Maria Friedrich Ernst von Weber (18-19 November 1786 - 4-5 June 1826) was a German composer, conductor, pianist, guitarist and critic, one of the first significant composers of the Romantic school.
Weber's operas Der Freischütz, Euryanthe and Oberon greatly influenced the development of the Romantic opera in Germany. Der Freischütz came to be regarded as the first German "nationalist" opera, Euryanthe developed the Leitmotiv technique to a hitherto-unprecedented degree, while Oberon anticipated Mendelssohn's music for A Midsummer Night's Dream and, at the same time, revealed Weber's lifelong interest in the music of non-Western cultures. This interest was first manifested in Weber's incidental music for Schiller's translation of Gozzi's Turandot, for which he used a Chinese melody, making him the first Western composer to use an Asian tune that was not of the pseudo-Turkish kind popularized by Mozart and others.
