Harmonic Highlights:

  • Features descending whole-step modulations via ii-V progressions, moving from Gmaj7 to Fmaj7 (via Gm7-C7) and then to Ebmaj7 (via Fm7-Bb7).
  • Frequent use of Am7b5 - D7b9 (iiø-V7b9) which often targets G minor but resolves both to minor (Gm7) and major (Gmaj7) tonics.
  • Employs extended turnarounds, combining classic iii-VI-ii-V cycles (e.g., Bm7-Em7-Am7-D7) with altered minor ii-V progressions.

Improvisation Focus: Arpeggio superimposition to precisely outline rapid, dense chord changes and their extensions.

Difficulty Rating: 5 (Advanced) due to the fast harmonic rhythm, frequent modulations, and use of altered dominants requiring sophisticated navigational skills.
