Harmonic Highlights:
- Frequent use of secondary dominants (F7, D7, G7) creating brief tonicizations and propelling harmonic motion.
- Prominent minor ii-V-i progression (Bm7b5 - E7b13) specifically targeting the relative minor (Am).
- Repetitive functional ii-V progressions (Gm7-C7, Am7-D7) establish and resolve tension throughout the form.
Improvisation Focus: Navigating ii-V-I progressions across various temporary tonal centers.
Difficulty Rating: 3 (Intermediate). Requires comfortable navigation of common jazz harmonic devices including secondary dominants and minor ii-V changes.
