Harmonic Highlights:
- Features a distinctive chromatic descending dominant 9b5 motif (F#9b5 to F9b5), establishing immediate harmonic tension and a ‘slipping’ quality.
- Employs an extended chain of descending altered dominant 7th chords (e.g., C9#11 down to Ab7b9), generating dense chromatic motion and sequential progression.
- Utilizes Dbmaj7 as a prominent harmonic anchor, often approached via tritone substitution (Ab7b9) and serving as a pivot for further dominant cycles (Bb7-Eb7-Ab7).
- Characterized by a high frequency of altered dominant chord voicings (e.g., 9#11, 7b9#5, b13) demanding precise melodic contouring and advanced harmonic awareness.
Improvisation Focus: Navigating altered dominant scales (e.g., Altered Scale, Lydian Dominant) over complex, chromatically shifting progressions.
Difficulty Rating: 5 (Advanced). Requires mastery of altered scales and sophisticated voice-leading over rapid, chromatically shifting dominant harmony.
