Harmonic Highlights:
- Prominent use of the IV7 chord (C7/G, C7) over the G tonic, creating a bluesy or subdominant character.
- Chromatic passing diminished chords, notably G07 leading to G7 and C#07 functioning as vii°7/V resolving to the dominant.
- A classic descending cycle of dominant chords (E7-A7b9-D7b9) provides a strong harmonic drive back to the G tonic.
Improvisation Focus: Navigating altered Mixolydian and diminished scales over the numerous dominant and passing diminished chords.
Difficulty Rating: 4 (Advanced Intermediate) - The rapid harmonic rhythm, complex dominant cycles, and chromatic passing chords demand precise scale and arpeggio execution.
