Edward Enrico Gerber's Fantasia is a complex contrapuntal work that demonstrates high levels of technical demand. It is distinctive for its rigorous structural integrity and virtuosic demands.
At Henle 6 this is an advanced piece that assumes fluent technique and rewards mature interpretation. The main demands: independent voices that must each sing on their own line; fine finger independence within the hand; and fast passage work that stays light and even at tempo.
At roughly 8 minutes, stamina and memory become part of the challenge — plan practice in sections.
The piece requires advanced finger independence and clarity of voice leading throughout fast-moving sections.
Comparable difficulty and character — good candidates for what to learn next.

Fantasia is rated Henle level 6 of 9 — advanced repertoire, roughly ABRSM grades 7–8.
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.
