Impromptu Frustrate (WoO 29) Piano Solo Arrangement with Chords, Metronome & BPM

Set within the harmonic domain of D Minor (one flat (B♭, with C♯ harmonic leading tone)), the score secures tonal focus on D. Expressive depth is enhanced through secondary pivots into F Major and dominant reinforcement via A Major. Harmonically, the progression Dm → G → C → F → E7 cycles smoothly through harmonic steps (F, E7) back toward the tonic. In terms of hand topography, D Minor yields a tragic, dignified key signature requiring careful hand shifts when raising the harmonic leading tone C♯.
