Harmonic Highlights:
- Tonic Elaboration: Features a sophisticated I - Iaug - I6 - Imaj7 sequence on the tonic, providing rich chromatic coloring.
- Chromatic Diminished: Employs passing diminished chords like F#07 (leading to Gm7) and G#07, demonstrating advanced voice leading.
- Temporary Tonicization: Includes a iiø-V7-i in G minor (Am7b5-D7b9-Gm), briefly tonicizing the supertonic.
- Subdominant Modulation: Introduces a ii-V in Bb major (Cm7-F7), indicating a temporary shift towards the subdominant key.
Improvisation Focus: Navigating temporary tonicizations and chromatic passing chords.
Difficulty Rating: 4. The frequent chromaticism and brief modulations demand precise chord-scale application and harmonic anticipation.
