Harmonic Highlights:

  • Establishes G minor as the tonal center with a strong i-V7 progression (Gm6 - D7b13), utilizing a b13 alteration on the dominant.
  • Features a classic minor iiø7-V7-i progression (Am7b5 - D7b9 - Gm6), emphasizing typical minor key resolutions.
  • Includes a V7/iv chord (G7b13) leading to Cm7, followed by a ii-V-I (F7 - Bb6) to the relative major (Bb).

Improvisation Focus: G Harmonic Minor scale.

Difficulty Rating: 3 (Intermediate). The frequent use of altered dominant chords and the modulation to the relative major require an intermediate grasp of harmony.
