Harmonic Highlights:
- The frequent descending major 7th chords (e.g., Cmaj7, Bbmaj7, Abmaj7) are often approached by their tritone substitutes or chromatic dominants (e.g., B7b9, A7#9, G7#9).
- Strategic use of diminished passing chords, such as Eb07 connecting Cmaj7/E to Dm7, adds color and smooth voice leading.
- Temporary modulations via clear ii-V-I progressions to non-tonic keys (e.g., Cm7, F7, Bbmaj7) expand the harmonic landscape.
- Chromatic dominant movements like D-Db7-C7 create tension and drive the progression forward.
Improvisation Focus: Navigating altered scales and arpeggios precisely over frequent, fast-moving dominant 7th chords.
Difficulty Rating: 5 (Advanced). The rapid harmonic rhythm, frequent modulations, and abundant use of altered dominant and diminished chords demand high harmonic fluency.
