  • Harmonic Highlights:

    • Frequent chromatic sideslip from G69 to Ab69, creating an immediate non-diatonic harmonic color before returning to the tonic.
    • A strong cycle of dominant chords (E7-A7-D7) functions as V/ii - V/V - V/I, propelling motion back to the key center of G major.
    • Inclusion of Bb07 as a chromatic passing diminished chord, creating tension and a brief “outside” moment before resolving to the ii chord, Am7.
  • Improvisation Focus: Chord-tone targeting with chromatic embellishment.

  • Difficulty Rating: 4 (Advanced Intermediate). The rapid chromatic shifts, dense dominant cycles, and non-diatonic diminished chords require sophisticated harmonic understanding and agile execution.
