Harmonic Highlights

  • Utilizes a gospel-influenced IV7 (Eb7) to #IV°7 (E°7) progression, resolving to the tonic over its fifth (Bb/F) to create a “church” blues aesthetic.
  • Features a sophisticated bebop turnaround using a descending diatonic sequence (Dm7-G7-Cm7-F7), effectively cycling through the circle of fourths.
  • Employs a secondary dominant (C7) as the II7 chord, emphasizing a bright, Mixolydian-inflected “funk” sound before the final cadence.
  • The structure is a 12-bar blues variant that replaces traditional static harmony with dense, functional ii-V-I movements.

Improvisation Focus Bb Blues scale integrated with the Bb Mixolydian mode.

Difficulty Rating 2/5; the 12-bar blues foundation is accessible, though the rapid turnaround requires familiarity with secondary dominants and basic bebop vocabulary.
