Harmonic Highlights:
- The Ab07 following Fmaj7 creates a striking color, functioning as a passing diminished chord or a rootless D7b9 substitute leading to Gm7.
- A sequence of Fmaj7 - F7#5 - Bbmaj7 - Eb7 showcases a secondary dominant to the IV chord, followed by a backdoor dominant or tritone substitution.
- Descending chromaticism is prominent with the E7 - Eb7 - D7 dominant chain, generating tension before the Gm7 resolution.
- The progression Am7b5 - D7b9 - G7 introduces a iiø-V7b9 leading to a temporary tonicization of C major or a pivot to the IV chord.
Improvisation Focus: Navigating altered dominant scales (e.g., Altered Scale, Lydian Dominant) to address the various non-diatonic V7 chords.
Difficulty Rating: 4 - The frequent use of altered dominants, passing diminished chords, and temporary modulations demands sophisticated harmonic understanding.
