Harmonic Highlights
- The recurring “Bbmaj7, Ebm/Bb” motif establishes a distinctive modal color, juxtaposing a minor iv chord from the parallel minor over the Bb major tonic’s root.
- Classic iiø-V7alt-i progressions (Am7b5-D7#9-Gm7) firmly anchor the G minor tonality, utilizing prominent dominant alterations.
- Frequent use of altered dominant chords (D7#9, D7#5) resolves chromatically to the G minor tonic, increasing harmonic tension.
- A brief, standard ii-V (C7-F7sus-F7) in the relative major (Bb) provides a contrasting tonal area before returning to the main harmonic theme.
Improvisation Focus Navigating altered dominant scales over V7 chords while outlining the G minor tonality.
Difficulty Rating 4 (Advanced). The blend of traditional minor harmony with unique modal colors and frequent altered dominants demands harmonic sophistication.
