Harmonic Highlights:
- Prominent extended dominant chain:
Em7b5 (iiø7/vi) - A7b9 (V7/vi) - D7 (V7/ii) - G7 (V7/V)creates intense forward motion. - Frequent use of secondary and altered dominants (
A7b9) generating chromatic tension and requiring specific scale choices. - Juxtaposition of complex dominant cycles with straightforward
I-vi-ii-Vprogressions in F major, providing harmonic variety.
Improvisation Focus: Altered Dominant Scales
Difficulty Rating: 5 (Advanced) – Requires mastery of altered scales, navigating rapid dominant cycles, and intricate voice leading across dense harmonic changes.
