Schubert Piano Sonata no. 17 in D major 'Gasteiner', D. 850

Franz Schubert's Piano sonata in D major D. 850, Op. 53, known as the Gasteiner, was written in 1825, while the composer was staying in the spa town of Bad Gastein. A year later, it became only the second of his piano sonatas to be published. The sonata is noticeably faster in tempo than many other of Schubert's sonatas (unusually for him, the first movement is marked vivace). The first and four movements place a considerable technical demand on the soloist.
