Harmonic Highlights:
- Extensive use of ii-V-I progressions to tonicize multiple keys, including bVI (Bbmaj7), parallel major (Dmaj7), bVII (Cmaj7), and relative major (Fmaj7).
- Features a distinctive non-diatonic ii-V (Bm7-E7, targeting A major) that resolves unexpectedly back to the bIII (Fmaj7), adding harmonic tension.
- Frequent shifts between the D minor tonic and its parallel major (Dmaj7), alongside other major key modulations, creating varied tonal colors.
Improvisation Focus: Navigating rapid ii-V-I progressions and modulations to multiple temporary tonal centers.
Difficulty Rating: 4 (Advanced Intermediate) Explanation: Requires proficient knowledge of ii-V-I changes across several keys and adapting to frequent tonal shifts, including non-standard resolutions.
