Harmonic Highlights

  • Employs an elongated 24-bar form that expands the traditional minor blues structure through phrase repetition and rhythmic displacement.
  • Substitutes the standard IV chord with a bVI7 (Db7), introducing Lydian Dominant textures that pivot sharply back to the tonic Fm7.
  • Incorporates a momentary modal interchange via the IVmaj7 (Bbmaj7), providing a bright, non-diatonic contrast to the prevailing F minor tonality.
  • Utilizes a functional ii-V turnaround (Gm7b5 to C7#9) to provide a traditional hard-bop resolution within an otherwise modern modal framework.

Improvisation Focus F Minor Pentatonic/Blues scale fluency, integrated with Db Lydian Dominant to navigate the bVI7 shifts.

Difficulty Rating 3 (Intermediate): The 24-bar structure and the unexpected Bbmaj7 require more harmonic precision than a standard blues, though the primary key center remains stable.
