An early Allegro by Mozart, K. 72a, likely a movement from a sonata, exhibits the composer's early command of form and melodic invention. It's a bright and cheerful piece requiring dexterity and rhythmic precision.
Maintain a light and even touch throughout the rapid scale and arpeggio figures.

You should be comfortable at Henle level 5 — meaning you can already play level 4–5 pieces cleanly. Learning it one level early is possible as a stretch piece, but more than that usually leads to months of frustration.
