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.
