Harmonic Highlights:

  • The Bbmaj7 (bVI) provides a melancholic, colorful departure from D minor.
  • Db07 functions as a leading-tone diminished chord (C#07) resolving to D7#5.
  • Frequent use of #5 altered dominants (D7#5, G7#5) injects significant tension.
  • The G7#5 to Cm7 progression establishes a temporary tonicization of C minor.

Improvisation Focus: Altered Scale (Super Locrian) for navigating the tension-rich dominant chords.

Difficulty Rating: 4/5 The prevalence of altered dominant chords and diminished harmony requires sophisticated scale and arpeggio choices.
