Franz Peter Schubert was an Austrian composer of the late Classical and early Romantic eras. Despite his short life, Schubert left behind a vast oeuvre of more than 1,000 compositions, including over 600 Lieder and other vocal works, seven complete symphonies, sacred music, operas, incidental music, and a large body of piano and chamber music. Among these are the songs "Gretchen am Spinnrade", "Erlkönig" and "Ave Maria"; the Trout Quintet; the Symphony No. 8 in B minor (Unfinished); the Symphony No. 9 in C major ; the String Quartet No. 14 in D minor ; the String Quintet in C major; the Impromptus for solo piano; the last three piano sonatas; the Fantasia in F minor for piano four hands; the incidental music to the play Rosamunde; the song cycles Die schöne Müllerin and Winterreise; and the song collection Schwanengesang.
