  • Harmonic Highlights:

    • Prominent use of the ii-V-I progression in both the tonic minor (Am7b5 D7b13 Gm6) and its relative major (Cm7 F7 Bbmaj7).
    • Frequent application of altered dominant chords (D7b13), providing tension and color before resolving to the tonic minor.
    • Includes a descending cycle of dominant-like movement in the relative major section (Cm7 F7 Bbmaj7 Ebmaj7).
    • Features a bVII7 chord (Gb7) after the minor tonic, often functioning as a backdoor dominant or chromatic passing chord.
  • Improvisation Focus: Navigating the interplay between G minor and Bb major harmonies using appropriate minor scales and altered dominant scales.

  • Difficulty Rating: 3: It features fundamental ii-V-I progressions in major and minor, making it accessible, but the altered dominants and harmonic rhythm require focused attention.
