In hindsight, it is not difficult to view all compositions by Franz Schubert dating from 1828 as his swan song. Schubert suspected that he did not have much time left. One time in particular at the beginning of October, some six weeks before his death, he wrote as follows to a Leipzig publisher: “Among other items, I have written three sonatas for piano solo, which I would like to dedicate to Hummel. [...] I have performed the sonatas already in various locations to great acclaim.” But here the wish was father to the thought, as finally the works were not completed until September 1828. There was no reply to his offer. The three Sonatas D. 958 (in C minor), D. 959 (in A major) and D. 960 (B-flat major) were not published until 1839, more than 10 years after Schubert’s death: they were issued in three volumes – with a dedication to Robert Schumann.
