Harmonic Highlights:

  • The Ebm7 (minor iv) resolving to Bbmaj7/D provides a distinct melancholic color and chromatic embellishment.
  • Secondary dominants like G7#9 (V/ii) create tension and effectively lead to diatonic minor chords (Cm7).
  • The Fm7-Bb7 ii-V progression briefly tonicizes Eb major, diversifying the harmonic landscape.
  • The Em7b5 to Ebm7 chromatic shift offers sophisticated inner voice leading and harmonic interest before resolution.

Improvisation Focus: The Melodic Minor scale and its various modes for altered dominant and chromatic minor chords.

Difficulty Rating: 4 (Advanced Intermediate). The inclusion of complex chromatic minor chords and altered dominants requires a solid understanding of advanced harmonic substitution and altered scale application.
