- Harmonic Highlights:
- Extensive use of secondary ii-V progressions, particularly to vi (Am7b5-D7b9) and V (Gm7-C7b9).
- Frequent altered dominant chords (D7b9, D7b13, C7b9) enhance harmonic tension and color.
- The Gb07 functions as a chromatic diminished chord, providing a brief but impactful passing tension.
- Brief tonicization of the IV chord (Eb) via its ii-V (Fm7-Bb7).
- Improvisation Focus: Altered Scale
- Difficulty Rating: 4 (Advanced Intermediate). Frequent secondary ii-V changes and altered dominant chords require an advanced understanding of harmonic implications.
