Harmonic Highlights:
- The prominent Fmaj7 to Ebmaj7 alternation establishes a modal interchange bVIImaj7 sound, borrowing from the parallel minor or Mixolydian mode.
- A secondary dominant V7/IV is present with the F7 resolving to Bbmaj7, temporarily tonicizing the subdominant.
- The progression from Bbmaj7 to Bbm6 introduces the melancholic ivm6 chord, a classic minor subdominant modal interchange.
- Standard ii-V-I progressions (Gm7-C7-Fmaj7) provide clear diatonic resolution to the tonic.
Improvisation Focus: Modal Interchange Adaptation
Difficulty Rating: 3 (Intermediate) - This standard requires a solid grasp of modal interchange and secondary dominants beyond basic diatonic harmony.
