Harmonic Highlights:
- Rich tonic coloration featuring Cmaj7, C7, C6, and the chromatically expressive Caug chord.
- Extensive use of secondary dominant cycles, notably iiø7-V7 movements that temporarily tonicize diatonic minor chords (e.g., F#m7b5-B7 to Em).
- Alternating major and minor ii-V-I progressions provide intricate harmonic movement while maintaining the C major key center.
Improvisation Focus: Navigating the interplay of major and minor ii-V-I progressions and their derived secondary dominant alterations.
Difficulty Rating: 4 (Advanced Intermediate). The frequent use of half-diminished chords, secondary dominants, and chromatic tonic variations demands a sophisticated harmonic understanding.
