  • Harmonic Highlights

    • Frequent ii-V-I progressions firmly establish the Eb major tonic.
    • Secondary dominants (e.g., C7, F7) are employed to extend harmonic tension and drive towards target chords.
    • The progression Abmaj7 - Dm7b5 - G7b9 - Cm7 introduces a strong, temporary minor key cadence, adding harmonic depth.
  • Improvisation Focus Chord-scale improvisation, especially navigating dominant seven chords.

  • Difficulty Rating 3 (Intermediate). The use of secondary dominants and temporary modulations requires a good grasp of functional harmony.
