Franz Peter Schubert (31 January 1797 – 19 November 1828) was an Austrian composer of the late Classical and early Romantic eras. Despite his short lifetime, Schubert left behind a vast oeuvre, including more than 600 secular vocal works (mainly lieder), seven complete symphonies, sacred music, operas, incidental music, and a large body of piano and chamber music. His major works include "Erlkönig" (D. 328), the Piano Quintet in A major, D. 667 (Trout Quintet), the Symphony No. 8 in B minor, D. 759 (Unfinished Symphony), the "Great" Symphony No. 9 in C major, D. 944, the String Quintet (D. 956), the three last piano sonatas (D. 958–960), the opera Fierrabras (D. 796), the incidental music to the play Rosamunde (D. 797), and the song cycles Die schöne Müllerin (D. 795) and Winterreise (D. 911).
The largest number of his compositions are songs for solo voice and piano. Schubert also composed a considerable number of secular works for two or more voices, namely part songs, choruses and cantatas. He completed eight orchestral overtures and seven complete symphonies, in addition to fragments of six others. While he composed no concertos, he did write three concertante works for violin and orchestra. Schubert wrote a large body of music for solo piano, including eleven incontrovertibly completed sonatas and at least eleven more in varying states of completion, numerous miscellaneous works and many short dances, in addition to producing a large set of works for piano four hands. He also wrote over fifty chamber works, including some fragmentary works. Schubert's sacred output includes seven masses, one oratorio and one requiem, among other mass movements and numerous smaller compositions. He completed only eleven of his twenty stage works.
