Harmonic Highlights:
- Standard ii-V-I progressions (Fm7-Bb7-Ebmaj7) establish the tonal center and provide foundational movement.
- The Bbm6 chord functions as a sophisticated “backdoor” dominant approach to Ebmaj7 when followed by Bb7, adding a distinct color.
- A chain of secondary dominants (Gm7-C7-F7) temporarily shifts harmonic gravity, creating forward momentum.
- Chromatic passing diminished chords (F#07) and altered dominants (Bb7#5, C7b9) introduce tension and colorful resolutions.
Improvisation Focus: Navigating ii-V-I progressions and their common alterations.
Difficulty Rating: 4 (Advanced Intermediate). The presence of secondary dominants, altered dominants, and chromatic passing chords requires a solid understanding of advanced harmonic concepts.
