Harmonic Highlights:

  • Features an opening A7 chord often functioning as V/V, leading into the primary Am7 D7 G6 ii-V-I progression.
  • Employs clear ii-V-I movements not only to the tonic (Am7 D7 G6) but also temporarily to the subdominant (Dm7 G7 Cmaj7).
  • Utilizes a D7#5 for an altered dominant sound before the tonic, alongside a classic Cm6-D7 (iv-V) progression.

Improvisation Focus: Navigating clear functional harmony, particularly the ii-V-I cycles and temporary tonicizations.

Difficulty Rating: 3 (Intermediate). The tune combines standard ii-V-I movements with secondary dominant functions and temporary modulations, requiring attentive harmonic interpretation.
