Harmonic Highlights:

  • The parallel tonic shift from D6 to Dm6 utilizes modal interchange, introducing the minor third (F natural) to create a distinct Samba-Exaltação mood.
  • The B7(b13) functions as a secondary dominant (V/ii), providing a chromatic bridge to the standard ii-V-I turnaround (Em7-A7-D6).
  • Extended harmonic duration—frequently holding a single chord for four measures—emphasizes internal rhythmic syncopation over rapid vertical navigation.

Improvisation Focus: D Major scale with a shift to D Dorian or Melodic Minor over the Dm6 sections.

Difficulty Rating: 2/5. The harmonic rhythm is slow and the progressions are largely diatonic, though the major-to-minor modal shifts require precise melodic targeting.
