Harmonic Highlights:

  • The opening Ebmaj7 (Vmaj7) provides a softer, less dominant-resolved approach to the tonic, diverging from a traditional V7.
  • Db7 (bII7) introduces a distinct non-diatonic color, leading to Fm7 (vi) for a characteristic deceptive or reharmonized progression.
  • Frequent secondary dominant usage, such as Bb7 (V/Eb) and F7 (V/Bb), adds harmonic tension and propulsive movement.
  • The extended Cm7-F7 (iii-V/Bb) progression creates a characteristic harmonic vamp often used for melodic development.

Improvisation Focus: Chord-scale theory application.

Difficulty Rating: 4 (Advanced) because of the frequent harmonic shifts and non-diatonic chords, demanding precise understanding of chord-scale relationships and voice leading.
