Harmonic Highlights:
- Clear and consistent ii-V-I progressions (Fm7-Bb7-Eb6) establishing the tonic.
- Frequent use of secondary dominants, notably the iii-VI7-ii progression (Gm7-C7-Fm7).
- A concise tonicization to the subdominant (IV) via Bbm7-Eb7-Abmaj7.
- An extended cycle of dominant chords (Abmaj7-D7-G7-C7) creating strong forward harmonic momentum.
Improvisation Focus: Navigating ii-V-I progressions with their respective Dorian and Mixolydian modes.
Difficulty Rating: 3 (Intermediate). The standard features both predictable diatonic movements and several non-diatonic dominant chains requiring careful harmonic navigation.
