Harmonic Highlights:
- Employs ii-V-I progressions leading to the IV major chord (Ebm7-Ab7-Dbmaj7), creating a bright subdominant extension from the home key.
- Features an unexpected ii-V-I progression to C minor (Dm7-G7-Cm7), temporarily tonicizing the iii minor chord of Ab major.
- Includes the F7#9 chord, functioning as a V7/ii, which introduces an altered dominant sound and strong pull to the Bbm7.
- Characterized by successive ii-V movements (e.g., Cm7-F7, Dm7-G7) that frequently shift temporary key centers, demanding agile navigation.
Improvisation Focus: Fluid application of Dorian and Mixolydian modes to accurately outline the numerous ii-V progressions.
Difficulty Rating: 4 (Advanced Intermediate) - The frequent and non-diatonic temporary modulations, combined with altered dominants, require advanced harmonic understanding and improvisational agility.
