- Harmonic Highlights:
- Features a temporary tonicization of the subdominant (Ab major) via a Bbm7-Eb7-Abmaj7 progression.
- Includes a prominent secondary ii-V (Am7b5-D7#9) resolving to the iii minor (Gm7), utilizing an altered dominant (D7#9).
- Employs a diminished chord (F#07) acting as a V-substitute leading to Gm7, followed by a V/ii secondary dominant (C7).
- Improvisation Focus: Understanding the function and appropriate scales for secondary dominants and ii-V changes within and outside the primary key.
- Difficulty Rating: 4 (Advanced Intermediate). The frequent use of secondary dominants, altered dominants, and brief modulations demands a sophisticated harmonic understanding.
