Johann Baptist Cramer was a master of the classical étude style, and his divertimentos are essentially polite, structured salon pieces. They favor balance, symmetry, and technical clarity common to the late 18th century.
At Henle 4 this is an intermediate piece that expects secure technique and real attention to phrasing. The main demands: Alberti-bass accompaniment kept quiet and even under the melody; precise articulation — the difference between crisp and blurred is the piece; and fast passage work that stays light and even at tempo.
Beyond that, expect fine finger independence within the hand.
The technical requirement is a crisp, even touch in the scale passages and clarity in the left-hand accompaniment patterns.
Comparable difficulty and character — good candidates for what to learn next.
A level or two down with the same spirit — ideal if this piece is still out of reach.
Where this piece's skills lead: slightly harder works making similar technical demands.
Lesser-known works by the same hand, at a comparable level.
Divertimento No.1, M.7.05 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.
