Harmonic Highlights:

  • Strong tonic emphasis is evident through sustained Gmaj7/G6 sections and frequent resolutions to the I chord.
  • The predominant harmonic movement centers around the diatonic ii-V-I progression (Am7-D7-Gmaj7).
  • Bb07 functions as a chromatic diminished chord, introducing tension and color before resolving to the Am7-D7.

Improvisation Focus: The G Major scale and its diatonic modes (A Dorian, D Mixolydian) are the most crucial for navigating the ii-V-I progressions.

Difficulty Rating: 2/5 - Its foundation on repetitive diatonic ii-V-I progressions makes it highly accessible, with the Bb07 providing a manageable chromatic alteration.
