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.
The E13b9 chord sounds distinctive, with a dominant 13th flat 9 character. Its notes are E, G#, B, D, F, C#. This chord is commonly heard in jazz.
