Harmonic Highlights:
- A prolonged Dm11 vamp establishes a modal (D Dorian) or static harmonic foundation before the main progression.
- A unique descending minor 7th sequence (Dm7-Cm7-Bbm7-Cm7) introduces early harmonic movement and chromaticism.
- Extensive Coltrane-style modulations occur through ii-V-I cycles descending by a major third (e.g., Fm7-Bb7#5#9-Ebmaj7).
- Frequent use of highly altered dominant chords (#5#9) creates intense tension and dramatic resolutions throughout the progression.
Improvisation Focus: Navigating altered scales and arpeggios across rapidly shifting, distantly related tonal centers.
Difficulty Rating: 5 (Advanced). Requires mastering complex altered dominant voicings and navigating rapid, distantly related modulations.
