Practice Note

This dominant color is associated with the half-whole diminished scale and commonly resolves to a major chord; it is not a standard minor-key ii–V–i sound because its natural 13 clashes with the minor tonic’s b6. The 5th is a frequent omission in piano voicings, while the b9 and guide tones carry the tension.
