ABSTRACT
The piano sonatas of Schubert written before 1818 demonstrate the composer's great fondness for experimentation with the sonata as a genre. The individual movements as well as the piano pieces are, however, for the most part not complete, but rather fragments. Among these are a number that have hardly been considered or, indeed, have remained unknown. Take, for example, the Rondo in C (D309A), a fragment dated 16 October 1815 that until recently had been in private hands and not available for the public. Unnoticed until now is also the first version of the first movement of the Sonata in D flat major (D568) from June 1817. The final version comprises three more bars than the first one: Schubert here expands the proportions of a phrase that modulates from D flat minor to A flat major (bars 28-33).
