Harmonic Highlights
- The progression utilizes a sudden chromatic shift from the tonic G minor into B major (Bmaj7, G#m7), moving to a distant, non-diatonic key center.
- Incorporates Lydian #11 colors (Gbmaj9#11) and suspended dominant sounds (Gb7sus), creating impressionistic tension that bypasses traditional functional resolution.
- Features chorale-style voice leading via slash chords (D/Bb, Bmaj7/F#), providing a linear bass movement that stabilizes the volatile harmonic shifts.
Improvisation Focus
Voice leading across chromatic key centers, focusing on common tones and guide-tone connectivity.
Difficulty Rating
4/5. The frequent, abrupt transitions to unrelated keys require high-level harmonic visualization and a developed ear for non-diatonic melody.
