This is No.5 from a set of 6 short piano pieces by Schubert called "Moments Musicaux" or "Musical Moments". Although this one is supposed to be played quite fast (Allegro Vivace) it is quite forgiving in terms of speed, and is therefore suitable as a practice piece for any pianist of moderate ability.
