Harmonic Highlights:

  • Primarily features diatonic ii-V-I progressions (Am7-D7-Gmaj7), establishing a clear G major key center.
  • Employs a secondary dominant (E7b9 leading to Am7) to extend harmonic movement within the tonic area.
  • Includes a brief, temporary modulation to the IV (Cmaj7) via a preceding ii-V (Dm7-G7).
  • The unusual Cm/maj7 chord introduces a distinctive chromatic tension point, adding color before the final ii-V.

Improvisation Focus: Targeting G Major scale/modes and adapting for chromatic alterations like the E7b9 and Cm/maj7.

Difficulty Rating: 3 (Intermediate) - While largely diatonic, the secondary dominant (E7b9) and unique Cm/maj7 chord demand specific harmonic understanding.
