When Günther Henle founded his Urtext publishing house in 1948, the first work in the catalog was the two-volume edition of Mozart's piano sonatas. Even today they still bear the numbers HN1 and HN2. Over the years, both volumes have been revised several times so that the musical text always reflects the latest in scholarly research. The manuscripts have survived many of Mozart's sonatas, and he made slight changes to the text before printing some of his works. For this reason, we provide both versions in such cases. The editor's preface and critical commentary provide detailed information concerning all sources and questions regarding the text.
