Harmonic Highlights
- Features frequent ii-V-I progressions, notably to the relative minor (Am) and subdominant (Fmaj7).
- Employs altered dominant chords (E7alt, C7alt) to create significant tension and provide colorful resolutions.
- Includes chromatic passing diminished harmony (Ab07) to smooth voice leading between diatonic chords.
- Utilizes the bVII9 chord (Bb9) as a blues-inflected dominant substitute leading to the tonic area.
Improvisation Focus Altered dominant scales for tension-release over V7alt chords.
Difficulty Rating 4 (Advanced) – The rapid harmonic rhythm, frequent modulations, and prevalence of altered dominants demand a sophisticated improvisational approach.
