Harmonic Highlights:

  • The opening I - bVII (Ebmaj7 - Dbmaj7) movement utilizes constant-structure harmony to create a Lydian/Mixolydian atmosphere, bypassing traditional dominant-tonic tension.
  • The sudden shift to Cmaj7 represents a chromatic modulation to a non-diatonic VI major, briefly establishing a new tonal center via an Am9-Dm9-G13 turnaround.
  • The integration of the minor subdominant (Abm/maj7) and modal interchange chords like Ebm6 (functioning as a borrowed iv6) creates the signature “saudade” harmonic tension.

Improvisation Focus: Navigating non-functional root movements and chromatic mediant shifts through precise voice-leading.

Difficulty Rating: 4/5: The non-standard modulations and frequent shifts between unrelated major-seventh chords demand sophisticated modal awareness and advanced melodic navigation.
