In just 20 years of creative activity, Schubert transformed the humble lied (“art song”) into emotionally all-embracing microcosms, and expanded the Classical symphony, string quartet, and piano sonata into epic fusions of melodic radiance and structural ingenuity. His early compositions reveal his love of Mozart, especially his Symphony No. 5 in B-flat major, D. 485 (1816). By then he had dutifully followed his father into teaching, the torment of which lit the touchpaper of his genius for songwriting—he composed more than 600 in total. Song remained at the heart of his output, inspiring two song cycles of searing emotional power: Die schöne Müllerin, D. 795 (“The Fair Maid of the Mill,” 1823) and Winterreise, D. 911 (“Winter Journey,” 1827), and several instrumental masterpieces, including the Wanderer-Fantasie, D. 760 (1822) for solo piano. His final works, especially the String Quintet in C major, D. 956 (1828), reach out emotionally way beyond his 31 years. Incredibly, much of Schubert’s music went unpublished during his lifetime—a Viennese music dictionary of the 1830s didn’t even mention him. It wasn’t until Schumann, Liszt, Mendelssohn, and particularly Brahms ensured that his music was printed and heard that the full extent of his achievement was revealed.
