Harmonic Highlights:
- Prevalence of the I-VI-ii-V progression, frequently incorporating dominant extensions like G7b13.
- Effective use of the secondary dominant A7 (V/ii) to introduce the Dm7 chord.
- Distinctive ii-V-i resolution (F#m7b5-B7b9-Em7) creating a strong, temporary tonicization of the iii minor chord.
Improvisation Focus: Navigating ii-V-I progressions and outlining chord tones, particularly during the temporary tonicizations.
Difficulty Rating: 3 (Intermediate). The tune combines familiar ii-V-I cycles with a key harmonic departure via tonicization of the iii chord.
