Harmonic Highlights:

  • The opening Bb7-Ab7-G7sus sequence introduces a distinctive blues-infused dominant chain, featuring a bVII7 (Ab7) leading to a V/C sus (G7sus).
  • Extended dominant function is prominent with the C7-F7 (V/V-V) progression, building tension before returning to the tonic Bb.
  • Slash chords like Cm7/F and G7/F suggest sophisticated bass line counterpoint or pedal point, adding harmonic depth and movement over the dominant F.

Improvisation Focus: F Mixolydian and Bb Mixolydian scales, integrated with the Bb blues scale.

Difficulty Rating: 4 (Advanced Intermediate). The blend of blues harmony with functional progressions and extended dominants requires a solid grasp of altered scales and sophisticated voice leading.
