Another sonata-allegro movement from Schubert's prolific output, this piece is more robust and harmonically adventurous than D.571. It displays a mature grasp of sonata form with distinct thematic material and dramatic development.
Requires control of dynamic contrasts and precise execution of rapid scale passages.

You should be comfortable at Henle level 4 — meaning you can already play level 3–4 pieces cleanly. Learning it one level early is possible as a stretch piece, but more than that usually leads to months of frustration.
