Harmonic Highlights:

  • Prominent use of ii-V-I progressions, tonicizing F major and Bb major away from the G minor key center.
  • Application of chromatic dominants and tritone substitutions (e.g., Bb7, A7, Eb9) creating unexpected voice leading.
  • The G7#11 functions as a secondary dominant (V7/Cm) leading to a temporary C minor region.

Improvisation Focus: Navigating various dominant 7th scale applications (Mixolydian, altered scales).

Difficulty Rating: 4 (Advanced Intermediate) - The rapid key center shifts and frequent altered dominant chords require a sophisticated harmonic understanding.
