D flat Dominant ninth

The dominant ninth chord extends a dominant seventh by adding the ninth, giving you classic dominant pull with extra color and breadth. In charts, this appears as C9: tense, expressive, and still clearly functional.

How it's built

Use 1-3-5-♭7-9. In C9: C-E-G-B♭-D. In practical voicings, the fifth is often omitted so the guide tones (3 and ♭7) plus color (9) stay clear.

Usage

In jazz, soul, funk, blues, and modern pop, the 9 is a go-to dominant color when you want richness without losing direction toward resolution.

Examples

• Jazz turnarounds - V9 resolving to I or i
• Funk and soul comping - colorful, groove-forward dominant stabs
• Pop arranging - refined dominant lift in pre-chorus and bridges

Play

Lead the 3 and ♭7 smoothly, and place the 9 where it sings above the voicing. Keep the midrange uncluttered so the dominant function remains obvious.
