Harmonic Highlights

  • Frequent i-iv (Dm7 to Gm7) movement establishes a strong modal minor foundation throughout the A sections.
  • The Bb7#11 (bVI7) acts as a chromatic approach to the dominant (V7), introducing Lydian Dominant textures to the minor tonality.
  • Integration of the relative major (F major) via a Gm7-C7-Fmaj7 sequence provides brief tonal relief from the D minor center.
  • Standard minor ii-V-i cadences (Em7b5-A7b9-Dm7) serve as the primary structural anchor for harmonic resolution.

Improvisation Focus D Minor Blues scale for maintaining melodic cohesion over the repetitive i-iv modal movements.

Difficulty Rating 2 (Beginner-Intermediate): The progression is highly repetitive and relies on standard minor-key conventions and predictable shifts to the relative major.
