This Allegretto by Johann Christoph Friedrich Bach is a bright and cheerful piece typical of the Classical era. It features a clear melody and a lively, Alberti-bass accompaniment.
Maintain a light touch and crisp articulation throughout the piece.
Allegretto is rated Henle level 3 of 9 — late beginner repertoire, roughly ABRSM grades 4–5.
You should be comfortable at Henle level 3 — meaning you can already play level 2–3 pieces cleanly. Learning it one level early is possible as a stretch piece, but more than that usually leads to months of frustration.
A typical performance of Allegretto lasts about 2 minutes.
