The Piano Sonata No. 9 in E major, Op. 14, No. 1, is an early-period work by Ludwig van Beethoven, dedicated to Baroness Josefa von Braun, one of his patrons at that time. It was composed in 1798 and arranged – not transcribed[citation needed] – for string quartet by the composer in 1801 (Hess 34), the result containing more quartet-like passagework and in the more comfortable key of F major.
