Franz Schubert
Instrumental music, stage works and church music

That "appetite for experimentation" manifests itself repeatedly in Schubert's output in a wide variety of forms and genres, including opera, liturgical music, chamber and solo piano music, and symphonic works. Perhaps most familiarly, his adventurousness is reflected in his notably original sense of modulation; for example, the second movement of the String Quintet (D. 956), which is in E major, features a central section in the distant key of F minor. It also appears in unusual choices of instrumentation, as in the Sonata in A minor for arpeggione and piano (D. 821), or the unconventional scoring of the Trout Quintet (D. 667) for piano, violin, viola, cello, and double bass, whereas conventional piano quintets are scored for piano and string quartet.

Although Schubert was clearly influenced by the Classical sonata forms of Beethoven, Haydn and Mozart, his formal structures and his developments tend to give the impression more of melodic development than of harmonic drama. This combination of Classical form and long-breathed Romantic melody sometimes lends them a discursive style: his Great C Major Symphony was described by Robert Schumann as running to "heavenly lengths".
