Harmonic Highlights:

  • The core harmonic progression is iiø-V7-i in C minor, consistently featuring altered dominant voicings (e.g., G7#9, G7b13, G7b9).
  • A prominent section features a descending chain of dominant 7th chords (F9, Bb13, Eb7#9, Ab13, Db7#9), creating rapid, temporary shifts in tonicity.
  • Extensive use of altered dominant extensions (#9, b13, b9) on V7 chords provides tension and a modern harmonic vocabulary.

Improvisation Focus: The melodic minor scale and its derivative modes (especially Altered/Super Locrian) are crucial for navigating the various dominant chords.

Difficulty Rating: 4 (Challenging). The frequent altered dominants and rapid chord changes demand sophisticated harmonic awareness and scale choices.
