Ex Puls II expands upon the concepts of the first iteration, adding greater technical density and wider keyboard registers. It is a virtuosic display piece characterized by cascading runs and aggressive rhythmic motifs.
At Henle 6 this is an advanced piece that assumes fluent technique and rewards mature interpretation. The main demands: fast passage work that stays light and even at tempo; octave passages that demand a relaxed wrist to avoid tension; and wide stretches that reward larger hands and clever redistribution.
Beyond that, expect sharp dynamic and character contrasts held together in one arc.
Executing large, rapid jumps and expansive chordal figurations with perfect accuracy is the main obstacle.
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.
Ex Puls II (Op.79) 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.
A typical performance of Ex Puls II (Op.79) lasts about 5 minutes.
