Originally conceived as a grand piano sonata, this work embodies the early, explosive Lisztian style. It is characterized by its symphonic scale, heavy octave writing, and extreme dynamic range.
At Henle 8 this is concert repertoire: professional-level technique is the entry ticket. The main demands: big chords that need weight without harshness; wide stretches that reward larger hands and clever redistribution; and octave passages that demand a relaxed wrist to avoid tension.
Beyond that, expect sharp dynamic and character contrasts held together in one arc, and fast passage work that stays light and even at tempo.
At roughly 10 minutes, stamina and memory become part of the challenge — plan practice in sections.
The work requires immense physical stamina and the ability to project a massive sound throughout the keyboard range.
