- Standard ii-V-I progressions are frequently employed, notably to Eb, Ab, and implied F.
- Features a “backdoor” ii-V (Abm7-Db7) that leads to a subsequent ii-V (Gm7-C7) rather than a direct bVImaj7 resolution.
- Incorporates a highly chromatic descending dominant chain (Db7-C7-B7-Bb7) before the final ii-V-I, generating significant tension.
Improvisation Focus: Navigating ii-V-I changes and their various substitutions across multiple key centers.
Difficulty Rating: 4 (Advanced). The rapid harmonic rhythm, frequent modulations, and complex dominant alterations demand a sophisticated understanding of chord-scale theory and harmonic function.
