The Sonata in E-flat major (Hob. XVI/38, L. 51) is a keyboard sonata composed by Joseph Haydn, also referred to as a piano sonata. The three-movement work was published by Artaria in 1780 in a set of six sonatas dedicated to the sisters Katharina and Marianna Auenbrugger.
The sonata has three movements:
The first movement is in sonata form. It is monothematic, in that the movement only presents and significantly develops one distinct theme.[1]
The second movement is a siciliana. The third is in da capo form, akin to a minuet and trio.[2] [3] The two movements are linked by an attacca direction: the second movement has an open ending on a G-major chord; the third movement follows immediately, and that chord becomes the submediant triad (with raised third) of the new movement's key of E-flat major.[4]
