Harmonic Highlights:

  • Nuanced exploration of the D minor tonic using Dm, Dmb6, Dm6, Dm7, implying various minor scale qualities (natural, Dorian, melodic).
  • Extensive application of altered and substituted dominant chords, notably B7#5#9, Bb7#11, and A7#5#9, creating sophisticated chromatic tension.
  • Strategic use of secondary dominants, like D7b9 (V7 of Gm), and subtle modal interchange elements from F major (relative major).

Improvisation Focus: Altered scales derived from the minor melodic mode.

Difficulty Rating: 5 (Advanced). The dense use of altered dominants and complex substitutions requires deep harmonic knowledge and precise scale application.
