Harmonic Highlights:
- The frequent use of Dm7-G7-Cmaj7 establishes a strong C major tonality through standard II-V-I progressions.
- A secondary II-V-I progression, Em7-A7b9-Dm7, introduces a temporary dominant function targeting the D minor supertonic.
- Fm6 functions as a borrowed subdominant minor, adding color and a minor plagal feel before resolving back to diatonic harmony.
- The F#7 chord provides a striking chromatic dominant, resolving unconventionally to Fmaj7, creating unique harmonic tension.
Improvisation Focus: Navigating II-V-I progressions by targeting chord tones and using appropriate modes (e.g., C Ionian, D Dorian, G Mixolydian, A Altered).
Difficulty Rating: 3 (Intermediate). While featuring familiar II-V-I movements, the inclusion of altered dominants, borrowed chords, and an unconventional F#7 chord elevates its complexity beyond a beginner standard.
