Harmonic Highlights

  • Employs a minor ii-V-i (Am7b5 - D7b9 - Gm7) to establish the relative minor tonality immediately, creating a somber, melancholic character.
  • Features a chromatic tritone substitution (Gb7) acting as a bridge between the tonic Gm7 and the ii-V of the subdominant (Fm7 - Bb7).
  • Demonstrates a clear shift from the G minor opening to a traditional major cadence (Cm7 - F7 - Bbmaj7), highlighting the relationship between parallel major/minor centers.
  • Uses secondary dominants like C7 (V/V) to provide strong harmonic pull toward the dominant F7 before resolving to the Bb major tonic.

Improvisation Focus The interplay between G Harmonic Minor (for the minor ii-V-i) and Bb Major/Ionian scales.

Difficulty Rating 3 (Intermediate): Requires the ability to fluidly navigate rapid transitions between relative minor and major functional cycles.
