Harmonic Highlights:
- Extended dominant cycles (e.g., Ab13-Db7-Gb13) create prolonged tension and intricate voice leading.
- Frequent use of altered dominants (B9b5, G7b9, G7b5) introduces chromaticism and unexpected harmonic color.
- Non-functional or oblique dominant movements (e.g., F, B9b5, Dm7, Eb9) contribute to a sense of harmonic unpredictability and tonal ambiguity.
Improvisation Focus: Altered Scale
Difficulty Rating: 5 (Advanced) – Its rapid shifts between implied tonic centers and pervasive use of altered dominants demand advanced harmonic understanding and improvisational agility.
