Piano Sonata in C major, D 613 (Schubert)

The Piano Sonata in C major D 613 is an unfinished piano sonata written by Franz Schubert in April 1818.

I. Moderato
Only a fragment exists, ending after the development with an implied cadence in E major.

(II. Adagio, D. 612)
According to Martino Tirimo, Schubert's Adagio in E major, D. 612 is most likely the middle movement of this sonata.

III.
Lacking a tempo indication, this movement is in the style of a siciliana. It is incomplete, and ends at what is presumably the end of the development.
