Harmonic Highlights
- Prominent application of ii-V-I progressions (e.g., Fm7-Bb7 to Eb, Gm7-C7 to F) as a core structural element.
- Strategic use of secondary dominants (e.g., G7 targeting C minor, C7 targeting F major) to generate temporary tonicizations.
- The
Eø7chord functions as a chromatic passing sonority or a tritone substitution, creating distinct harmonic color. - The
Bb/Fchord serves as a V7sus4 substitute or provides a Lydian color over the dominant, enriching the harmony.
Improvisation Focus Navigating the frequent ii-V progressions and their related chord-scales.
Difficulty Rating 3 (Intermediate) - It features numerous ii-V changes and secondary dominants requiring attention to chord-scale relationships beyond simple diatonic playing.
