Harmonic Highlights
- Employs sophisticated minor tonic variations (Am7, Am/maj7, Am6) providing a rich, evolving home chord quality.
- Features recurrent C7#11 (bIII7#11) as a chromatic, often non-functional dominant, creating significant harmonic tension and color.
- Showcases a distinct modulation to B major (Bmaj7, C#m7, F#7) from A minor, followed by a pivot back via Bmaj7 to E7.
- Integrates borrowed chords from parallel major (Bm7) and secondary dominants (D7) for added harmonic interest.
Improvisation Focus Navigating the Lydian Dominant sound (e.g., on C7#11) and its often unexpected, non-functional resolutions.
Difficulty Rating 4 (Advanced Intermediate) - The frequent non-functional chromaticism, distant modulations, and specific dominant voicings demand a sophisticated harmonic understanding.
