Harmonic Highlights

  • Features “side-slipping” from Fm6 to F#m6, creating chromatic tension that resolves to the subdominant Bbm7.
  • The bridge executes a sequence of rapid ii-V-I modulations ascending chromatically through D, Eb, and E major, requiring navigation of distant key centers.
  • Utilizes a functional minor ii-V-i (Gm7b5 - C7b9 - Fm6) to anchor the A sections in F minor, contrasting with the bright major resolutions in the bridge.

Improvisation Focus F Melodic Minor for the tonic sections and fluid voice-leading through the bridge’s shifting major keys.

Difficulty Rating 4 (Advanced) because the fast tempo and constant, non-diatonic modulations in the bridge demand high-level harmonic awareness and technical precision.
