Harmonic Highlights:

  • Utilizes frequent passing diminished chords (C#07, F#07) often acting as leading-tone diminished to subsequent chords.
  • Employs a sequence of secondary dominant 7ths (E7, A7, D7) to create a strong sense of forward motion and temporary modulation.
  • Features a tritone substitution (Db7 for G7), adding a bebop-era chromatic flavor to the dominant resolution.

Improvisation Focus: Mixolydian and Altered scales over the dominant 7th chords.

Difficulty Rating: 4 (Advanced Intermediate) - The extensive use of secondary dominants, diminished chords, and tritone substitutions requires a solid understanding of advanced harmonic concepts.
