This experimental work by Serban Nichifor employs contemporary techniques to explore the 'anamorphosis' of melodic themes. It is musically notable for its unstable harmonic center and sudden shifts in mood.
At Henle 6 this is an advanced piece that assumes fluent technique and rewards mature interpretation. The main demands: rubato that must breathe naturally without losing the pulse; several simultaneous layers, each needing its own dynamic level; and sharp dynamic and character contrasts held together in one arc.
Beyond that, expect precise articulation — the difference between crisp and blurred is the piece.
The player must have total control over tempo rubato to articulate the structural distortions of the theme.
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.

Choralis anamorphoticus is rated Henle level 6 of 9 — advanced repertoire, roughly ABRSM grades 7–8. In the RCM system it corresponds to about level 8.
You should be comfortable at Henle level 6 — meaning you can already play level 5–6 pieces cleanly. Learning it one level early is possible as a stretch piece, but more than that usually leads to months of frustration.
