Harmonic Highlights
- Static Abm7 tonicization: The initial eight bars establish a strong Dorian modal center, providing a stark contrast to the functional harmony that follows.
- Rapid sequential modulations: The structure utilizes ii-V-I sequences to cycle through distantly related keys including E major, Db major, and F major.
- Non-diatonic dominant links: Chromatic connectors and tritone substitutions (like A7 leading to Bbm7) create smooth transitions between the shifting tonal centers.
Improvisation Focus Navigating rapid ii-V-I sequences across multiple key centers.
Difficulty Rating 4/5. The contrast between long modal stretches and fast-moving, chromatic functional passages requires high-level harmonic agility and visualization.
