Harmonic Highlights:

  • Modal vamp between iv minor and v minor/iv in two distinct tonal centers (Ab minor and F# minor), establishing a suspended, oscillating feel.
  • Abrupt, non-diatonic transitions to bVImaj7#11 (Bmaj7#11, Amaj7#11) from the minor vamps, introducing bright Lydian harmony.
  • A subsequent sequence of ascending Maj7#11 chords (Eb, F, Bb, C) expands the harmonic landscape with a flowing, Lydian-dominant character.

Improvisation Focus: Lydian mode.

Difficulty Rating: 4 (Advanced). The frequent non-diatonic Lydian shifts and modal ambiguity demand a sophisticated understanding of melodic and harmonic phrasing.
