This work, composed in June 1817, belongs to a prolific year for piano sonatas. Although it consists of three movements, the existence of a fourth movement, following the Moderato, Allegretto, and Scherzo, is suggested. In the case of this work, it is believed that theRondo D 506 final movement. The basis for this is the connection between the keys (E minor and E major), as well as the inscription "Sonata by Franz Schubert" found on a manuscript copy of this Rondo.

Although Sonata No. 6 is an early work, it was composed during a period when Schubert had decided to establish himself as an independent composer, and it can be said that it already transcends the realm of mere studies. It possesses a romantic atmosphere, and the soft sonorities of the second movement, in particular, make it an appealing work.
