  • Harmonic Highlights:

    • The distinctive Eb7 - Dm6 opening vamp creates a static, ambiguous harmonic oscillation, often functioning as a bVII7 to Vm or a tritone substitution leading to the dominant minor.
    • Features prominent ii-V-i progressions, notably in D minor (Em7b5-A7b9-Dm) and G minor (Am7b5-D7b9-Gm7), clearly establishing and resolving to key centers.
    • The bridge employs a temporary modulation to F major via a ii-V-I (Gm7b5-C7b9-Fmaj7), adding a bright contrast before returning to the minor tonality.
  • Improvisation Focus: Navigating minor ii-V-i progressions with appropriate altered dominant scales.

  • Difficulty Rating: 4 (Advanced Intermediate). The frequent minor ii-V-i progressions, altered dominants, and unique vamp demand a strong grasp of functional harmony and chromaticism.
