Harmonic Highlights

  • The progression centers on a i-IV movement (Cm7 to F7), creating a Dorian-inflected modal foundation that contrasts with traditional functional minor cadences.
  • Systematic use of diminished seventh passing chords (Db°7 and B°7) facilitates chromatic voice leading between the ii-V and tonic chords.
  • The composition utilizes “backdoor” ii-V sequences (Fm7 to Bb7) to resolve into the relative major (Ebmaj7), demonstrating frequent shifts in tonal center.
  • Minor ii-V-I cells (Dm7b5-G7-Cm7) are often embellished with altered dominant tensions to heighten the melancholic ballad aesthetic.

Improvisation Focus Voice leading through minor ii-V-I cells using the C Melodic Minor scale and altered dominant resolutions.

Difficulty Rating 3/5. While the slow tempo is forgiving, the frequent modulations and chromatic passing chords require a sophisticated understanding of minor-key functional harmony.
