Harmonic Highlights:
- Prominent use of diatonic ii-V-I progressions establishing the C major key center.
- Incorporates secondary dominants (e.g., A7b9 leading to Dm7) to create forward motion and color.
- Features a temporary modulation to the subdominant key of F major via a ii-V-I (Gm7-C7-Fmaj7).
- Utilizes altered dominant chords (G7b9, A7b9) and a passing diminished chord (F#07) for increased harmonic tension and chromaticism.
Improvisation Focus: Chord Tone Embellishment.
Difficulty Rating: 3 (Intermediate) – Requires navigating common jazz progressions, including secondary dominants and a brief modulation, which moves beyond basic diatonic understanding.
