Harmonic Highlights:
- Frequent use of altered dominant chords (G7b5, C7#11, F7#5) creates tension and drives motion through complex, non-diatonic extensions.
- The harmony showcases strong secondary ii-V-i progressions, notably Em7b5-A7-Dm7, temporarily tonicizing the dominant minor.
- Chromatic dominant substitution, such as B7 resolving to Bbmaj7, adds unexpected color and smooth, non-diatonic voice leading to major chords.
Improvisation Focus: Altered Dominant Scales
Difficulty Rating: 4 (Advanced-Intermediate). The frequent altered dominants, secondary ii-V-i progressions, and chromatic substitutions demand a deep understanding of complex harmonic concepts.
