Composed between 1774 and 1776, this is a three-movement piano sonata that possesses an overall bright atmosphere.

The first movement is in G major, 2/4 time, Allegro con brio. The first theme, characterized by an ascending melodic figure, is accompanied by double notes. In the development section (from m. 58), the second theme is primarily developed.

The second movement is a Minuet. It is in G major, like the first movement, and shifts to G minor in the Trio. Furthermore, the middle section of the Minuet itself modulates to D major, and the middle section of the Trio modulates to B-flat major.

The third movement, the Finale, is written in G major, 2/4 time, Presto. It is in rondo form. Its theme can be considered related to the themes of the first and second movements. Each time it reappears, it is varied with finer rhythms, increasing in vivacity towards the end of the piece.
