Harmonic Highlights:
- Strong diatonic ii-V-I progressions (Fm7-Bb7-Eb6) define the tonic Eb major.
- Prominent use of a subdominant minor ii-V-I (Bbm7-Eb7-Abmaj7) creating a temporary tonicization of the IV chord.
- Repeated ii-V movements (Fm7-Bb7) are used to prolong dominant tension before tonic resolution.
Improvisation Focus: Navigating clear ii-V-I progressions and their chord tones.
Difficulty Rating: 3 (Intermediate). The piece features clear diatonic harmony with a notable subdominant minor ii-V-I, requiring awareness of temporary tonicizations.
