Harmonic Highlights:

  • Tonic Modal Interchange: The immediate shift from Gmaj7/G6 to Gm6 introduces a melancholic parallel minor quality within the tonic.
  • Extended Dominant Cycles: The progression features a complex chain of ii-V movements, notably Bm7-E7#5-Am7-D9, showcasing altered dominants and multiple temporary tonicizations.
  • Chromatic Embellishment: Chords like Cm6-F7 (ii-V of Bb) and Bb07 add chromaticism and temporary modulations, expanding the harmonic landscape.

Improvisation Focus: Navigating dominant function with Mixolydian and Altered scales.

Difficulty Rating: 4 (Advanced Intermediate). It features frequent key center shifts, altered dominants, and a diminished chord before a complex ii-V cycle.
