Often referred to as the 'Great' Fantasia and Fugue, this work is noted for its spectacular virtuosic runs and the immense scale of its fugue. It stands out for its concert-hall brilliance and the demanding technical agility required by the Fantasia section.
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; fast passage work that stays light and even at tempo; and fine finger independence within the hand.
Beyond that, expect precise articulation — the difference between crisp and blurred is the piece, and continuous sixteenth-note figuration that must ripple, not chatter.
At roughly 12 minutes, stamina and memory become part of the challenge — plan practice in sections.
The rapid, unrelenting sixteenth-note runs require absolute finger precision and stamina.
