Schubert’s last three piano sonatas, written between the spring and autumn of 1828, the last year of his life, are often considered as a group, sharing many elements of structure and form. He performed the three sonatas at a concert for his friends on 28 September 1828, and in October offered them to his publisher, Probst, who was not interested. Schubert’s health, already weak, rapidly deteriorated and he died on 19 November 1828, at the age of thirty-one.
