- The piece prominently features the parallel minor (Em9) at its outset, establishing a melancholic, modal quality despite the stated E major key center.
- Frequent deployment of altered dominant chords (B13, B7#5#9, C#13) creates significant tension, often implying blues or minor key resolutions.
- The use of Fmaj9/B and Fmaj9#11/B reharmonizes the V7sus chord (B7sus4(b9,#11)), introducing a sophisticated Lydian-Phrygian dominant sound.
- A striking tritone substitution occurs with Bb13 and Bb7#5 leading directly to Ebmaj7, executing a bold, distant modulation away from the primary E tonal center.
Improvisation Focus: Navigating altered dominant scales and their precise resolutions.
Difficulty Rating: 5 (Advanced) due to the complex modulations and frequent use of altered dominant and suspension voicings requiring sophisticated harmonic understanding.
