Harmonic Highlights
- Frequent use of Fm7-Gbmaj7, a distinct non-diatonic progression suggesting modal interchange from Bb minor or chromatic mediant movement.
- Temporary tonicization of D minor (iii) through the Em7b5-A7b9-Dm6 ii-V-i progression.
- Strategic application of secondary dominants (e.g., Bb7 resolving to Ebmaj7) and altered dominants (F7#5) for heightened tension and resolution.
Improvisation Focus Melodic Minor Modes.
Difficulty Rating 5 (Advanced). Its frequent non-diatonic progressions, altered dominant chords, and temporary modulations demand a deep understanding of advanced chord-scale relationships.
