Harmonic Highlights

  • Employs a standard minor ii-V-i (Am7b5–D7b9–Gm7) to anchor the G minor tonality.
  • Utilizes a descending bass line (Gm7–Gm7/F–Ebmaj7) creating a classic “line clichĂ©” movement from the tonic to the submediant.
  • The bridge features rapid, “side-slipping” ii-V sequences that modulate from Bb major down to Ab major.
  • Incorporates chromaticism via the Bm7–E7 to Bbm7–Eb7 transition, requiring precise navigation of shifting tonal centers.

Improvisation Focus G Dorian scale for the primary groove, switching to melodic minor over dominant chords and chord-tone arpeggiation for the bridge’s sequential ii-V-I patterns.

Difficulty Rating 3/5. The A section is a straightforward minor vamp, but the bridge demands quick thinking to navigate descending ii-V sequences in distant keys.
