Harmonic Highlights
- Prominent use of the bVIImaj7 (Bbmaj7) and its secondary dominant F7 (V/bVII), creating a strong modal interchange feel.
- The D7#5 (V/G) functions as a colorful secondary dominant, building tension before the tonic’s dominant G7b9.
- The C#07 operates as a chromatic passing diminished, creating tension and resolving chromatically to Cm7 (C#07 to Cm7 shares G and Bb).
Improvisation Focus C Harmonic Minor Scale.
Difficulty Rating 3 (Intermediate). The frequent use of secondary dominants, altered V7 chords, and chromatic diminished chords requires a solid understanding of minor key harmony and voice leading.
