Composed between 1789 and 1790, this sonata is dedicated to the pianist Marianne von Genzinger. It consists of three movements.

First Movement

The first movement, in E-flat major, is marked Allegro and is in 3/4 time. This sonata movement is relatively large in scale among Haydn's piano sonatas. Before the recapitulation (m. 132-), a one-measure phrase with a cadenza-like character is inserted. The opening theme suggests a dialogue between the left and right hands. The transitional passage (m. 13-) leading into the second theme (m. 28-) is so well-established that it could be counted as one of the themes; indeed, in the development section (m. 65-), this element is developed first. Subsequently, elements of the first theme are also seen (m. 25-). The movement concludes with an ascending scale in the right hand, its upper voice ending on the third scale degree.

Second Movement

The second movement, Adagio e cantabile, is in 3/4 time and written in B-flat major, the dominant key of the first movement. Although in ternary form, its total length of 124 measures makes it relatively large among Haydn's slow movements. In the middle section (m. 57-), a leading line first appears in the left hand. In the third section (m. 81-), the opening theme of the first section is rhythmically varied with fine ornamental note values.

Third Movement

The third movement, Finale, is marked Tempo di Menuetto and is in 3/4 time, in the same key of E-flat major as the first movement. Written in rondo form, a lively character pervades the entire movement, a stark contrast to the graceful second movement.

As described, this piano sonata is, overall, relatively large in scale among Haydn's piano sonatas.
