- Harmonic Highlights:
- Extended chromatic descending bass lines (e.g., D-C#-C-B) create intricate voice leading over ii-V movements.
- Frequent secondary dominants and passing chords (e.g., D7/F#, C7/E) facilitate smooth, colorful transitions.
- Prominent temporary ii-V-I modulation to Eb major (Fm7-Bb7-Ebmaj7) before resolving back to D minor.
- Altered dominant chords like A7#9 heighten tension within the iiø-V-i cadences.
- Improvisation Focus: Precise chord-scale navigation, emphasizing altered dominants and temporary modulations.
- Difficulty Rating: 5 (Advanced). Its dense harmonic rhythm, rapid modulations, and complex chord alterations demand high theoretical and technical proficiency.
