Harmonic Highlights:

  • Features classic IIm7-V7-IMaj7 progressions in the tonic key of Eb.
  • Employs a descending bass line movement from the tonic (Ebmaj7 - Ebmaj7/D - Cm7).
  • Includes a significant temporary modulation to G major via ii-V-I progressions (Am7b5 - D7b13 - Gmaj7).
  • Utilizes secondary dominants (e.g., C7 to Fm7) and non-diatonic dominant chords (Ab7) for chromaticism.

Improvisation Focus: Navigating chord tones and arpeggios through modulations and temporary key centers.

Difficulty Rating: 4 (Advanced Intermediate). The temporary modulations and use of altered dominant chords require attentive harmonic awareness.
