  • Harmonic Highlights:
    • Initial movement strongly tonicizes the relative major (F major) with the Gm7-C7-F6 progression.
    • Frequent use of secondary ii-V patterns, specifically Am7-D7, leading to the G minor/major region.
    • A classic minor key iiø-V-i (Em7b5-A7-Dm) firmly re-establishes the D minor tonic.
  • Improvisation Focus: D melodic minor scale and its associated modes.
  • Difficulty Rating: 3 (Intermediate) - It requires navigating minor key harmony, relative major tonicization, and several distinct ii-V patterns.
