Part of Beethoven's exercises under Albrechtsberger, this piece reflects his early fascination with Bach and strict form. It is a dense, high-energy contrapuntal work.
At Henle 7 this is a late-advanced work — the technical demands are serious and sustained. The main demands: independent voices that must each sing on their own line; fine finger independence within the hand; 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.
Maintaining the motoric pulse in both hands while articulating complex subject entries is the primary challenge.
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.
