Harmonic Highlights:
- Relies heavily on diatonic ii-V-I progressions (Fm7-Bb7-Ebmaj7) to firmly establish Eb major as the primary key.
- Presents a clear modulation to Ab major via a strong ii-V-I sequence (Bbm7-Eb7-Abmaj7).
- Utilizes a secondary dominant (F7, V7/Bb) to introduce tension and further harmonic direction.
- The repeated Gm7 (iii chord) creates momentary harmonic prolongation or a deceptive resolution before returning to ii-V.
Improvisation Focus: Navigating ii-V-I changes using chord tones and specific modal scales (e.g., Mixolydian over V7, Dorian over ii minor).
Difficulty Rating: 3 (Intermediate). While core progressions are common, the clear modulation to Ab and use of secondary dominants demand attentive harmonic understanding.
