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.
