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) ā Requires understanding of minor key harmony, secondary dominants, and navigating altered dominant tensions.
