Harmonic Highlights

  • The progression utilizes a temporary modulation to the dominant (Bb major) via a ii-V-I sequence (Cm7 - F7 - Bbmaj7), requiring the improviser to pivot between Eb and Bb tonal centers.
  • A descending bass line (Gm7/D - Cm7 - Cm7/Bb - Am7b5) creates a linear, chromatic transition that bridges the diatonic chords back to the primary ii-V turnaround.
  • Functional secondary dominants like G7b13 (V/vi) and C7 (V/ii) add harmonic tension and directional pull toward the Cm7 and Fm7 targets.

Improvisation Focus Guide tone navigation to smoothly connect shifting key centers and secondary dominant resolutions.

Difficulty Rating 3/5. The 3/4 waltz meter and frequent shifts to the dominant key require more rhythmic and harmonic agility than a standard diatonic ballad.
