Harmonic Highlights:
- Prominent backdoor ii-V (Fm7-Bb7) resolving to Fmaj7 (I).
- Recurring Abø7 (diminished 7) as a chromatic passing chord or altered dominant substitute.
- Strong tonicization of D minor via Em7-A7b13-Dm7 (ii-V-i).
- Use of D7/A as an inverted V/ii, anticipating motion towards Gm7.
Improvisation Focus: Precise chord tone outlining, emphasizing extensions and chromatic voice leading.
Difficulty Rating: 4 (Advanced Intermediate) - The frequent modulations, use of backdoor dominants, and chromatic diminished chords demand a strong command of harmony and melodic navigation.
