Harmonic Highlights:

  • Prominent V7b9/IV to IVmaj7 progression (G7b9 resolving to Cmaj7).
  • Frequent use of altered dominant chords (E7#5, G7#5) to build tension.
  • Strategic deployment of secondary dominant cycles (e.g., A7 -> Dm7, D7 -> G7).
  • Inclusion of a passing diminished chord (Eb07) often functioning as a G7b9 substitute.

Improvisation Focus: Altered Scale application over dominant chords.

Difficulty Rating: 4. The frequent altered dominants and passing diminished chords require precise harmonic understanding and scale application beyond basic diatonic playing.
