Mozart's 'Andante' K.616 is a beautiful and expressive piece, often transcribed from a musical clock. It is distinguished by its exquisite melodic writing, subtle harmonic colors, and gentle, flowing accompaniment.
Develop a sensitive touch and careful pedaling to create a warm, singing tone and shape the melodic phrases expressively.
Andante (K.616) is rated Henle level 4 of 9 — intermediate repertoire, roughly ABRSM grades 5–6. In the RCM system it corresponds to about level 5.
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.
