Harmonic Highlights:
- Persistent Em7b5 (viø7) after the tonic Gm, hinting at G melodic minor before the standard iiø7-V7b9 resolution.
- Chromatic dominant preparation with Eb7#11 (bVI7#11) directly preceding the V7b9 (D7b9), adding significant tension.
- Exploration of descending bass lines and diminished harmony (Gm7/F, E07, Bb07) for advanced voice-leading and secondary dominant functions.
Improvisation Focus: G minor scales (Harmonic and Melodic).
Difficulty Rating: 4 (Advanced Intermediate). The harmonic vocabulary, including altered dominants and non-diatonic chords, demands a strong theoretical understanding.
