Harmonic Highlights:
- The opening Em7 - A/E vamp establishes a static, E Phrygian-infused modal color over the v chord of A minor.
- A sophisticated descending chromatic progression (Am7 - Gm7 - F#m7b5 - F13) generates strong tension, resolving effectively to Em7.
- Frequent temporary dominant functions (e.g., A7 as V7/iv) and chromatic voice leading create constant harmonic motion and reinterpretation.
- The Am7-Gm7-F#m7b5-B7b9 sequence provides a clear iiø7-V7b9 resolution to Em7, reinforcing the minor dominant (v) function.
Improvisation Focus: E Phrygian mode.
Difficulty Rating: 5 (Advanced). The consistent use of non-diatonic chords, complex chromatic movements, and modal vamps demands sophisticated harmonic understanding and execution from improvisers.
