Harmonic Highlights:

  • Frequent establishment of temporary minor tonics (Gm, Bm7, Am) through ii-V progressions, creating a constantly shifting harmonic landscape.
  • The prominent Gm chord and its associated ii-V-I sequences (e.g., Dm7, A13b9 leading to Gm) suggest a strong secondary tonal area in G minor, contrasting with the stated E minor key center.
  • A direct Em7b5 - E7b9 - Am progression functions as a clear ii-V-i modulation to A minor, further diversifying the harmonic centers.
  • The Gmb6 chord introduces a distinct, often melancholic color, hinting at a G melodic minor or Phrygian dominant flavor.

Improvisation Focus: Melodic Minor Scale and its various modes across shifting tonal centers.

Difficulty Rating: 5 (Advanced). The rapid, often deceptive modulations between distinct minor key centers and the pervasive use of altered dominants demand sophisticated harmonic agility.
