Harmonic Highlights:

  • Prominent use of the V7b13 chord (G7b13) for the C minor tonic, emphasizing the characteristic minor key dominant sound.
  • Frequent deployment of secondary dominants, notably C7b13 resolving to Fm7 (V7/iv), adding harmonic interest.
  • Oscillation between the tonic C minor and its relative major, Ebmaj7, utilizing clear V7-I progressions (Bb7-Ebmaj7).
  • Incorporation of altered tensions (b9, b13, #5) on dominant chords (G7b9, C7b13, Bb7#5) for enhanced resolution.

Improvisation Focus: Harmonic minor scale (and its modes, particularly Phrygian Dominant).

Difficulty Rating: 3 (Intermediate) – Requires understanding of minor key harmony, secondary dominants, and navigating altered dominant tensions.
