Harmonic Highlights
- Blues-infused tonic (Bb6, Bb7) and subdominant (Eb7) harmony establishes a clear blues form with a jazz overlay.
- Chromatic passing diminished chord (C#0) leads dynamically into an altered dominant (G7#9) for enhanced voice leading.
- Standard ii-V-I progressions (Cm7 F7 Bb7) provide foundational jazz harmonic movement.
- Intriguing chromatic dominant approach (Gb7/E -> F7) creates sophisticated tension before the V7 chord.
Improvisation Focus Mixolydian scales and altered dominant concepts.
Difficulty Rating 4 (Advanced) - Requires navigating blues harmony, altered dominant chords, and sophisticated chromatic passing movements.
