Harmonic Highlights
- The progression utilizes a chromatic descent via tritone substitution (D7#11 to Db7) to bridge the gap between dominant cycles and the tonic.
- Persistent use of the tonic-to-submediant relationship (Fm to Db7) creates a blues-inflected minor vamp that defines the section’s harmonic rhythm.
- An extended dominant turnaround (G7b9b13 to C7b9) provides a strong minor ii-V-i resolution, employing altered tensions to drive melodic gravity toward the Fm6 tonic.
Improvisation Focus F Melodic Minor scale, which effectively navigates the tonic Fm6 and provides the necessary altered tensions for the C7b9 dominant.
Difficulty Rating 3/5: Navigating the rapid succession of altered dominants and chromatic substitutions requires a solid grasp of voice leading and minor-key functional harmony.
