Harmonic Highlights

  • The Bbmaj7 (bVIImaj7) and Ab7 (bVI7) chords provide a distinct minor mode color, leading into the G7 (V7).
  • A strong chromatic dominant approach is evident with Ab7 resolving directly to G7.
  • Temporary ii-V progressions like Cm7-F7 and Gm7-C7 create movement and transient tonicizations.
  • The Gb07 diminished chord functions as a chromatic passing harmony, adding tension and leading voice movement.

Improvisation Focus C Harmonic Minor Scale.

Difficulty Rating 3 (Intermediate). The mix of standard minor ii-V-i, chromatic dominants, and passing ii-V changes requires thoughtful navigation.
