Harmonic Highlights:
- Frequent tonicization of the subdominant (Bb major) via ii-V-I progressions (Cm7 F7 Bbmaj7), creating brief shifts in tonal focus.
- Sophisticated exploration of the minor chord quality through an extended Am sequence (Am, Amaug, Am6, Am7, Am/maj7), showcasing varied tensions and alterations within a single root.
- Incorporation of non-diatonic dominant chords, such as the backdoor dominant (Eb7) and the Lydian dominant (Bb7#11), adding color and complexity beyond diatonic harmony.
Improvisation Focus: Chord-Scale Theory application to navigate the frequent shifts in temporary tonal centers and specific altered chord qualities.
Difficulty Rating: 4 (Advanced Intermediate) - The extensive exploration of minor chord qualities and the frequent use of non-diatonic chords requires a deep understanding of advanced harmonic concepts.
