Harmonic Highlights
- The use of Gm7b5 (iiø) preceding the C7b9 (V7b9) creates a distinct tension before resolving to Fmaj7.
- A sophisticated backdoor dominant (Eb7#11) leads effectively to Fmaj7, providing harmonic color.
- A clear iiø-V7-i progression (Bm7b5-E7b9-Am7) temporarily modulates to the relative minor.
- The unexpected D7 to Abm7 movement introduces a tritone relationship, indicating complex harmonic detours.
Improvisation Focus Altered dominant scales are essential to navigate the frequent V7b9, V7#11, and V7b9 chords.
Difficulty Rating 4 (Advanced) - The rapid modulations, altered dominants, and unexpected chord progressions demand a high level of harmonic understanding.
