Harmonic Highlights:

  • Prominent use of altered dominant chords (A7b13, D7b13, D7b9) indicating a sophisticated, blues-influenced harmonic palette.
  • A distinctive chromatic dominant progression (Bb7-B7-C7) creates a strong, yet unusual, voice leading into the V chord.
  • Frequent deployment of ii-V progressions targeting both tonic and secondary areas (e.g., Am7b5-D7b9 resolving to Gm7, C7).

Improvisation Focus: Altered Scale (Super Locrian) on dominant chords.

Difficulty Rating: 4 (Advanced Intermediate). The frequent use of altered dominants and chromatic movements demands a solid understanding of advanced melodic and harmonic concepts.
