- Features an abundance of secondary dominants and their tritone substitutions (e.g., F#7b9, B7alt), driving continuous harmonic tension.
- Exhibits striking direct modulations, notably a move from C major to E major (
B7alt -> Emaj7), establishing a distant mediant tonal center. - Integrates several extended ii-V-I progressions (e.g., Gm7-C7-Fmaj7) that briefly tonicize keys outside the primary C major.
- Utilizes complex ii-V movements like F#m7b5-B7b9, often with altered extensions, reinforcing temporary key centers.
Improvisation Focus: Altered scale over the numerous dominant 7th altered chords.
Difficulty Rating: 4 (Advanced). The frequent, often distant modulations and prevalent use of altered dominants demand advanced harmonic understanding and agility.
