Harmonic Highlights:
- Frequent secondary dominants (e.g., E7 to Am7, A7 to D7) drive strong harmonic motion.
- Strategic tritone substitutions (Eb7 before Dm7, Ab7) introduce significant chromatic color and tension.
- Incorporation of non-diatonic and altered chords (F7, B7/D#, B7b9) creates unexpected voice leading and harmonic complexity.
- Repeated V/vi progressions (E7 to Am7) emphasize the minor ‘vi’ chord within the major key.
Improvisation Focus: Navigating altered dominant harmony and its numerous, often rapid, resolutions.
Difficulty Rating: 4 (Advanced Intermediate) - The density of secondary dominants, tritone substitutions, and chromatic alterations demands agile melodic and harmonic adaptation.
