Sonata for Arpeggione and Piano (D 821). Version for Violin and Piano by Anton Diabelli Nach den Quellen hrsg. von Christa Jost und Gerhart Darmstadt. Hinweise zur Interpretation von Gerhart Darmstadt. Fingersätze (Klavier) von Christa Jost Urtext Franz Schubert wrote his Arpeggione Sonata for piano and arpeggione, a hybrid instrument that was part guitar, part violoncello and fashionable at that time. The version for violin and piano has survived in a manuscript of parts from the days of Schubert which has become accessible only recently and is quite a sensation in the early 19th-century violin repertoire. The edition follows, for the most part, the text of Schubert's extant autograph and the contemporary violin part.
