Harmonic Highlights

  • Employs parallel minor modal interchange, shifting from Ebmaj7 (I) to Ebm7 (i) to create a sudden, moody shift in tonal color.
  • Features a secondary ii-V (Cm7-F7) that tonicizes the dominant (Bb), providing a brief structural departure from the tonic.
  • Exhibits a dramatic modulation to B major (enharmonic bVI), requiring navigation through a distantly related key center.
  • Uses a I7 to IV move (Eb7/G to Abmaj7) to reinforce the subdominant function before cycling back to the tonic.

Improvisation Focus Navigating modal interchange between the Eb Major and Eb Dorian scales.

Difficulty Rating 3/5: The abrupt modulation to B major and frequent shifts between parallel major and minor modes require intermediate-level harmonic awareness.
