Harmonic Highlights

  • Frequent II-V-I progressions are utilized, often tonicizing the IV chord (Fm7-Bb9sus-Ebmaj7) and the relative minor (Am7b5-D7b13-Gm7).
  • Chromaticism like F#0 leading to Gm7 provides a strong leading-tone diminished function to the vi chord.
  • Altered dominant chords (C7#9, C7b9, D7b13) create significant tension and color, demanding specific resolution.
  • The Abmaj7 briefly introduces a bVIImaj7 sound, suggesting modal interchange or a backdoor dominant approach.
