Harmonic Highlights:
- The G#° chord frequently functions as a vii°/vi, creating chromatic tension before resolving to Am7 or E7.
- Recurring secondary dominant progressions, such as Em7-A7 (iii-VI7) leading to Dm7, prepare ii-V movements.
- A clear iiø7-V7/vi progression is established with Bm7b5-E7, strongly tonicizing A minor.
- The C#m7b5 chord introduces an unexpected moment of advanced reharmonization or a brief modulation beyond the C major tonality.
Improvisation Focus: Emphasis on chord tones and guide-tone lines to delineate complex and non-diatonic harmonies.
Difficulty Rating: 4 (Advanced Intermediate). The frequent secondary dominants, diminished chords, and brief C#m7b5 require a solid grasp of non-diatonic harmony.
