Ex Puls by Andreas Sorg is a highly energetic contemporary work that emphasizes rhythmic tension and pianistic facility. Its distinctive feature is the persistent pulse that drives the harmonic sequences forward.
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; fine finger independence within the hand; and precise articulation — the difference between crisp and blurred is the piece.
Beyond that, expect sharp dynamic and character contrasts held together in one arc.
The primary challenge is maintaining a consistent, motoric tempo without losing clarity in the articulation.
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.
