Harmonic Highlights
- The piece prominently features an extended Gm7 (VI minor) at the outset, establishing a strong minor tonality despite the Bb major key center.
- A clear minor ii-V-i progression with Am7b5 - D7b9#5 strongly resolves towards G minor, emphasizing a consistent minor harmonic direction.
- The inclusion of Bbm7 - Eb7 introduces a non-diatonic ii-V, temporarily hinting at Ab major before returning to the prevailing G minor-oriented harmony.
Improvisation Focus G minor (harmonic/melodic) is crucial for navigating the prevalent minor tonality and altered dominants.
Difficulty Rating 4 (Advanced) - The frequent use of altered dominants, half-diminished chords, and non-diatonic ii-Vs requires sophisticated harmonic understanding and scale application.
