RH: C5 C#5 D5 D#5 E5 F5 F#5 G5 (ascending 16ths) LH: C2 — C#2 — D2 — D#2 — (descending octaves in contrary motion)
Then both hands meet in middle: | C4 E4 G4 C5 | (unison) — silence for an eighth note — | rest | Measures 17–24 (Development & climax) Broken chromatic clusters, presto sempre:
LH (syncopated off-beats, staccato): C2 — G1 — C2 — G1 — D2 — A1 — D2 — A1 — E2 — B1 — E2 — B1 — F2 — C2 — F2 — C2 — Sudden dynamic shift to ff , hands crossing occasionally: crack presto
RH jumps to low register: | G2 B2 D3 G3 | G3 D3 B2 G2 | LH leaps high: | G5 D5 B4 G4 | G4 B4 D5 G5 |
Mechanical, repeating 16th-note figures Left Hand (LH): Staccato jumps & octaves Measures 1–4 (Intro) RH: C5 - E5 - G5 - C6 (ascending arpeggio, 16ths) LH: C2 (staccato quarter) — rest — C2 — rest RH: C5 C#5 D5 D#5 E5 F5 F#5
Repeat pattern, then: RH: | C5 E5 G5 C6 | C6 G5 E5 C5 | D5 F5 A5 D6 | D6 A5 F5 D5 | | E5 G5 B5 E6 | E6 B5 G5 E5 | F5 A5 C6 F6 | F6 C6 A5 F5 |
Final 2 measures: RH + LH in parallel chords, 16th-note offbeats: (C-Eb-G) — rest — (C-Eb-G) — rest — (C-Eb-G) — (C-Eb-G) — (C-Eb-G-C) presto sempre: LH (syncopated off-beats
Then swap: RH descends chromatically from G6 down to C5 LH ascends from C1 to G3
