B Dominant seventh sharp ninth sharp eleventh

The 7♯9♯11 dominant combines upper bite and lift in one altered dominant color. ♯9 adds gritty pressure while ♯11 introduces bright expansion, yielding a chord that is both edgy and open. It is a strong choice when dominant tension must feel modern and energized.

Construction

Practical model: 1-3-5-♭7-♯9-♯11. In C: C-E-G-B♭-D♯-F♯. Function comes from 3/♭7; ♯9 and ♯11 shape the upper identity.

Usage

Useful in modern jazz, fusion, gospel, and cinematic transitions where dominant color should be sharp but not closed. It can bridge toward tonic or modal targets with high clarity.

Examples

• Altered V with bright modern edge
• Fusion comping with stacked upper tensions
• Pre-resolution dominant in dramatic cue writing

Play

Keep guide tones firm, then separate ♯9/♯11 by register to avoid blur. If density rises, remove inner notes rather than color tones.

Ear-training cues
