Oswin Keller's Ballade is a focused salon-style character piece that emphasizes charm and balanced phrasing. It provides a clear glimpse into the light, expressive style favored by late 19th-century pedagogical composers.
Control of articulation and delicate touch is required to avoid an overly percussive sound in the light textures.
Comparable difficulty and character — good candidates for what to learn next.
Ballade is rated Henle level 4 of 9 — intermediate repertoire, roughly ABRSM grades 5–6. In the RCM system it corresponds to about level 6.
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.
A typical performance of Ballade lasts about 4 minutes.
Ballade is available as free public-domain sheet music on IMSLP — the score is linked directly from this page.
