This Ballada by Borkowski is a piece defined by its melodic clarity and structural simplicity. It serves as an expressive character piece typical of 20th-century conservative piano repertoire.
The student needs to maintain a consistent cantabile line against a balanced, unobtrusive accompaniment.
Comparable difficulty and character — good candidates for what to learn next.
Ballada is rated Henle level 5 of 9 — late intermediate repertoire, roughly ABRSM grades 6–7. In the RCM system it corresponds to about level 7.
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.
A typical performance of Ballada lasts about 4 minutes.
