Harmonic Highlights:
- Prevalence of dominant 7th chords on tonic (C7) and subdominant (F7), creating a strong blues-jazz foundation.
- The F7 to Fm7 progression introduces modal mixture (Mixolydian to Dorian/Aeolian) over the subdominant function.
- A non-diatonic, descending chromatic sequence of minor 7th chords (Cm7, Dbm7, Bm7, Am7) injects advanced linear motion.
Improvisation Focus: Modal adaptation over non-functional chromaticism.
Difficulty Rating: 4 (Advanced). Requires navigating both conventional blues changes and complex non-functional chromatic shifts with precise modal application.
