Harmonic Highlights

  • Utilizes descending sequential ii-V movements (ii-V of B minor followed by ii-V of D major), creating a hallmark Legrand sense of melodic suspension.
  • Employs minor ii-V-i cells (iiΓΈ7 – V7b9 – im7) that pivot between the relative minor (B minor) and the home key.
  • Features sophisticated slash chords (F#7b9/B, A7b9/D) to smooth bass transitions and create harmonic ambiguity between dominant and tonic functions.
  • Incorporates chromatic secondary dominants (G#7#5) to facilitate modulations through half-step voice leading into minor ii-V chains.
  1. Improvisation Focus The Melodic Minor scale and its modes (specifically Locrian #2 and the Altered scale) to navigate the frequent minor-key functional cadences.

  2. Difficulty Rating 4/5: The rapid sequential modulations and reliance on altered minor harmony require advanced proficiency in voice leading and scalar fluidity across shifting tonal centers.
