Harmonic Highlights

  • Employs a quick transition from G minor to its relative Bb major using a standard ii-V-I sequence (Cm7-F7-Bbmaj7).
  • Features a sophisticated modulation to the distant key of D Major, facilitated by a chromatic C#dim7 passing chord.
  • Utilizes minor ii-V-i turnarounds (Dm7b5-G7b9-Cm7) to reinforce the dark, minor tonality before shifting to parallel and related major centers.
  • Uses secondary dominants like C7 and A7 to create functional motion toward subdominant areas and new key centers.

Improvisation Focus Navigating rapid key-center shifts (G minor to D major) using guide-tone connecting lines.

Difficulty Rating 4/5. The frequent modulations between minor and major keys and the distant shift to D major require advanced harmonic fluency and quick mental pivoting.
