The first movement of a sonata consisting of three movements: fast-slow-fast. In G minor, 2/4 time, and in sonata form. It is a virtuosic work where passages of scales and arpeggios sweep across a wide range. In this piece, perhaps due to the extensive development of the second theme's material in the development section, the recapitulation does not feature a restatement of the second theme, but primarily restates the material of the first theme.
