Harmonic Highlights:
- Extensive use of secondary ii-V-I progressions, such as
Gm7b5-C7to Fm andAm7-D7to G, constantly shifting harmonic focus. - Prominent non-diatonic chromaticism, exemplified by the
Gbm7chord creating a surprising tension before resolving toG7(V/Cm). - Recurring bluesy
Ab7(IV7) adds a soulful flavor, contrasting with the more complex diatonic and secondary dominants.
Improvisation Focus: Chord-scale theory and precise arpeggio navigation are paramount for covering the rapidly changing harmonies.
Difficulty Rating: 5 (Advanced) due to the dense harmonic rhythm, frequent modulations via secondary dominants, and unexpected chromatic substitutions.
