Violin Sonata (Haydn)
The Sonata for Piano and Violin Hob. XVV: 32 in G major by Joseph Haydn is the only authentic sonata for this instrumentation. Since there is also a trio version of it, this sonata is assigned to Group XV.
background
This violin sonata was probably composed on Joseph Haydn's first trip to London between January 1791 and June 1792. Although the occasion could not be clarified without a doubt, it is assumed that Haydn's Viennese Adlatus and copyist Johann Elßler published the piano sonata Hob. XVI: 49 with Artaria Verlag without Haydn's consent . As a replacement work, however, he only published this violin sonata two years later in Artaria Verlag. At about the same time he had the trio version of this violin sonata published by Preston in London. There is a manuscript in the Berlin State Library that was created a few years later. These show some changes, especially in the cello part. Therefore, some musicologists doubt the authenticity of the piano trio in relation to the cello.

The movement is in 6/8 time and in andante , has 158 measures and begins with an upbeat. The violin accompanies here first and corresponds to the course of the left pianist hand; only in bar 13 does it take part. In bar 25 the violin withdraws for a short time. In bar 80 the bass of the piano plays a G major run before the musicians stop in G minor for 28 bars (bars 81-108). A little restrained at the beginning, the violin takes over the piano theme. The theme is modified over runs (consisting of 16th triplets) . This movement ends with several G major triads.

In time 
, this allegro movement begins with the piano and the violin. The form of this movement corresponds to the sonata main movement form. In the first 22 bars, where the main theme appears, the two instrumentalists remain in conversation at eye level. From bar 23, where the secondary theme begins in the style of Italianità , the violin fades into the background at least in two small places. The implementation begins in measure 58. Up to and including bar 64 the violin accompanies with whole notes and then completely skips two bars. The topics, especially the secondary topic, are processed up to bar 90. The recapitulation begins in measure 91. The recapitulation roughly corresponds to the structure of the exposition. This movement ends here in measure 166 with G major triads.
