Fugue in F-sharp Minor (Op. 109) Urtext Performance Practice Edition & Harmonic Study Guide

Framed in F-sharp Minor, the score establishes F♯ through a key signature featuring three sharps (F♯, C♯, G♯, with E♯ leading tone). Harmonic variety is enriched through dialogue with the relative minor/major (A Major) alongside strong cadential support from C-sharp Major. Harmonically, the progression F#m → Bm → E → A → C#7 moves through balanced harmonic transitions (A, C#7) reinforcing the tonal root. Under the fingers, F-sharp Minor features an introspective minor topography where fingers two and three find natural placement on F♯ and G♯.

Assigned an overall Advanced rating (senior concert repertoire level (RCM Grade 10 to Licentiate)), the composition exercises manual independence. The central obstacle centers on balancing complex polyphonic textures, negotiating rapid register shifts, and sustaining virtuosic momentum. In performing articulated bass staccatos against singing right-hand runs, keep finger knuckles rounded and poised. For acoustic hygiene, employ syncopated pedal changes immediately following each chordal shift to avoid acoustic blurs. Practice Recommendation: isolate the polyphonic layers by singing one voice aloud while playing remaining lines pianissimo.

Rhythmic momentum flows through a 3/4 metric framework (simple triple meter). Calibrated to ♩ = 88 BPM (*Moderato grazioso*), the piece moves with a stable with buoyant, relaxed momentum pulse. As a practical study rule, shape the measure as a unified arc rather than counting three equal ticks.
