Harmonic Highlights

  • Employs chromatic “side-slipping” by moving from the tonic G69 to a non-diatonic Ab69 (bII69), creating immediate tension and neighbor-tone resolution.
  • Features a prominent secondary dominant chain (E7–A7–D7) that follows the cycle of fourths (VI7–II7–V7) to drive momentum back to the tonic.
  • Utilizes a Bb°7 passing chord between G/B and Am7, serving as a chromatic connector (bIII°7) to smooth the transition to the ii-V turnaround.

Improvisation Focus Arpeggio-based targeting that highlights the chromatic shifts between G and Ab major, coupled with Mixolydian or Lydian Dominant approaches over the extended dominant cycle.

Difficulty Rating 3/5: The harmonic structure is relatively straightforward, but the rapid “side-slipping” and typical Manouche tempo require high technical precision and fluid arpeggio connections.
