Harmonic Highlights
- The Fm7-Bb7 progression functions as a classic backdoor dominant (iv-bVII7) resolving to Cmaj7.
- A clear ii-V-I progression (Bbm7-Eb7-Abmaj7) executes a direct modulation to Ab major.
- The closing section features a series of non-diatonic major chords (Ebmaj7-Abmaj7-Dbmaj7), introducing significant chromaticism and harmonic displacement.
Improvisation Focus Navigating rapid modulations and diverse chord qualities using appropriate chord-scales.
Difficulty Rating 4 (Advanced) - The frequent key center shifts and prominent non-diatonic harmonies demand a high level of harmonic sophistication.
