Harmonic Highlights:
- Frequent major II-V-I progressions (Am7-D7-Gmaj7, Cm7-F7-Bbmaj7) demonstrating tonicization of related major keys and the parallel major from G minor.
- Extensive use of chromatic dominant chord movements and tritone substitutions (e.g., Gb7#5, Ab13, G7b9, E7b9) creating dense, tension-filled harmonic motion.
- Distinctive major 7th chord chains (Amaj7-Dmaj7-Gmaj7) moving by descending perfect fourths, a characteristic melodic harmonic device.
Improvisation Focus: Melodic minor modes for navigating altered dominants and various major/minor chord qualities.
Difficulty Rating: 5 (Advanced) - The fast-paced, highly chromatic modulations and extensive use of altered dominants require precise chord-scale application and harmonic agility.
