This Ballade by Stefan Zink explores the darker, more dramatic side of mid-century harmonic exploration. The piece relies heavily on sudden shifts in intensity and dynamics.
The biggest technical challenge is the controlled use of dramatic contrast to sustain the intensity through the piece.
Comparable difficulty and character — good candidates for what to learn next.
Ballade 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 Ballade lasts about 4 minutes.
