Harmonic Highlights:
- Establishes the key with recurrent I-vi-ii-V progressions in Eb major (Eb6-Cm7-Fm7-Bb7).
- Employs a secondary dominant (C7) as V7/F, leading to the ii chord (Fm7) in Eb major.
- Features a clear modulation from Eb major to G major, marked by a ii-V-I progression in G (Am7-D7-G6).
Improvisation Focus: Chord-scale application over ii-V-I progressions across different key centers.
Difficulty Rating: 4 (Advanced Intermediate) - The strong modulation to G major requires improvisers to quickly adapt to a new tonal center, moving beyond standard diatonic playing.
