Harmonic Highlights:

  • Initial tonic pedal point Cmaj7/G, C6/G establishes a stable but harmonically rich C major.
  • Dramatic chromatic mediant shift via Eb13 -> Abmaj7 (bIII7 to bVImaj7) provides a significant tonal departure.
  • Frequent use of altered dominant chords (G7#5#9, D13, G13) adds tension and color, leading to resolutions.
  • Integration of standard ii-V progressions with extended or deceptive sequences (e.g., Em7-Am7-D13).

Improvisation Focus: Emphasizing guide tones and chord extensions throughout frequent chromatic shifts and altered dominants.

Difficulty Rating: 4 (Advanced Intermediate). The blend of standard harmony with dramatic chromatic shifts and altered dominants presents a significant improvisational challenge.
