Entropia focuses on textural transformation and fluid passage work. The piece is distinctive for its seamless blending of chromaticism and non-traditional harmonic movement.
At Henle 5 this is a late-intermediate piece — technically substantial, with musical demands to match. The main demands: continuous sixteenth-note figuration that must ripple, not chatter; precise articulation — the difference between crisp and blurred is the piece; and chord voicing — bringing out one note inside a handful of others.
Maintaining an even, fluid touch throughout the persistent sixteenth-note patterns is the primary technical hurdle.
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.
Entropia 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.
