This Sonata is written as a single movement divided into sections.
An introductory Andantino directly leads into a Presto which contains the main theme and the transition to a more quiet secondary theme (Allegro moderato). After the development, the recapitulation is shortened: it contains a summary of the Introduction and it omits the main theme. Since the work lacks a clear tonality, the transition and the secondary theme are identically repeated.
In order to allow the interpreter as much freedom as possible to express the music as he feels, I chose not to include metronome marks. Pedal is completely marked only in those places where particular effects are required. The use of “una corda” is left to the interpreter’s taste.
