Harmonic Highlights
- Prolonged D7sus (V7sus of G minor) establishes an open, suspended sonority before unexpected harmonic shifts.
- Abrupt, non-diatonic modulation to Dmaj7, creating a Lydian color or a temporary major tonality contrasting the G minor key center.
- Usage of a ii-V-I leading to Gmaj7, highlighting the interplay between parallel major and minor keys.
- Classic iiø7-V7b9 progression (Am7b5-D7b9) serving as a strong reaffirmation of the G minor tonality after melodic and harmonic excursions.
Improvisation Focus Applying specific modal scales to each chord quality and temporary tonal center.
Difficulty Rating 5. The constant shifts between parallel major/minor, unexpected non-diatonic chords, and complex ii-V movements demand a high level of harmonic sophistication and modal fluency.
