  • Harmonic Highlights:
    • The extended Ebm7 vamp establishes a strong vi minor (Dorian/Aeolian) quality, providing a modal foundation within the F# major key center.
    • A surprising Gb7 (enharmonic F#7) functions as a blues-inflected I7 chord, introducing dominant quality on the tonic root following the minor vamp.
    • Significant non-diatonic chord usage is observed with Fm7 and Emaj7#11, indicating modal interchange and chromatic root movement.
    • The Emaj7#11 chord notably features the F# tonic as its #11, creating a distinctive Lydian sound that anchors the overall key center.
  • Improvisation Focus: Navigating modal shifts and chromaticism relative to the F# major tonic.
  • Difficulty Rating: 5 (Advanced) because it demands navigating complex non-diatonic harmony, chromatic root movements, and specific modal applications beyond standard diatonic progressions.
