Harmonic Highlights:
- Clear minor ii-V-i progressions in both C minor and the dominant’s relative minor, G minor.
- Extensive use of tritone substitutions, notably
Gb7for C7 resolving toFm7andB7for F7 leading toBb7. - Complex chromatic dominant cycles, such as
Eb7-Ab7-B7-Bb7, creating a rapid sequence of tension and resolution through secondary dominants and tritone subs.
Improvisation Focus: The Altered Scale (Super Locrian) for effectively navigating the frequent V7b9 chords and tritone substitutions.
Difficulty Rating: 4 (Advanced Intermediate). The rapid modulations, frequent tritone substitutions, and complex dominant cycles demand a strong grasp of advanced harmonic concepts.
