  • The progression Dm, Dmaug, Dm6 demonstrates a characteristic, chromatically rich development of the minor tonic, moving beyond a simple minor 7th sound.
  • A clear ii-V-i resolution in D minor is present with Em7b5, A7b9, Dm, featuring a prominent altered dominant.
  • The sequence Bbm6, C7, Fmaj7 establishes a temporary tonicization of F major, employing modal interchange (bVI) to facilitate the V-I cadence.

Improvisation Focus: Navigating altered dominant V7 chords (e.g., A7b9, D7#9) and understanding their resolution within minor key harmony.

Difficulty Rating: 4 (Advanced Intermediate). The piece requires familiarity with altered dominants, specific minor key ii-V-i voicings, and recognizing temporary modulations to the relative major.
