Harmonic Highlights:
- Frequent use of diatonic ii-V-I progressions (Dm7-G7-C6) establishes the home key of C major.
- Incorporation of the secondary dominant A7 (V7/ii) resolving to Dm7, adding common practice harmonic interest.
- Juxtaposition of both C6 and Cmaj7 voicings for the tonic chord, providing subtle color variation.
- A clear temporary tonicization to Bb major is indicated by the Cm7-F7 (ii-V) progression, departing from the home key.
Improvisation Focus: Targeting chord tones and appropriate modes (e.g., Dorian, Mixolydian) over ii-V-I changes and the temporary tonicization to Bb.
Difficulty Rating: 4 (Advanced Intermediate). The modulation to Bb major and slightly less common dominant functions require quick harmonic adaptation and ear training for improvisers.
