Harmonic Highlights

  • Frequent, abrupt modulations disrupt the G minor key center, notably the sudden shift to Bmaj7 and a G#m7 passage, creating chromatic third relations.
  • Sophisticated extended voicings like Gbmaj9#11 introduce color and potential Lydian dominant sounds, hinting at passing modulations or tritone substitutions.
  • Juxtaposition of diatonic minor ii-V-i (Am7b5, D7b9, Gm7) with non-functional bass lines (D/Bb) and highly chromatic dominant cycles.
  • Chord sequences often imply new temporary tonal centers, such as the ii-V-i in C minor (Dm7b5, G7b9) following distant harmonies.

Improvisation Focus Chord tones and melodic arpeggios are paramount to navigate the rapid, distant modulations.

Difficulty Rating 5 (Advanced) - The frequent, distant modulations and complex chord extensions demand a highly developed ear and extensive harmonic knowledge.
