Jef Tinel's Ballade voor piano is a lyrical work rooted in the late Romantic Flemish tradition. Its structure is episodic, favoring emotive melodic development over strict formal rigor.
The player must focus on maintaining a fluid, singing tone across the wide-ranging arpeggiated accompaniments.
Comparable difficulty and character — good candidates for what to learn next.

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.
