The 7♯11 dominant chord is a core Lydian-dominant sound: a functional dominant with a brighter, more modern upper color than plain 7 or 9 chords. The raised eleventh adds lift and openness while preserving forward harmonic pull.
Construction
A practical set is 1-3-5-♭7-9-♯11 with optional omissions. In C: C-E-G-B♭-D-F♯. In many voicings, 3 and ♭7 anchor function, and ♯11 becomes the defining color tone.
Usage
7♯11 appears in jazz, fusion, gospel, and cinematic writing whenever dominant function should feel bright rather than dark. It is especially useful in modal-functional blends and secondary dominant movement.
Examples
- Lydian-dominant V color before major or modal targets
- Fusion comping with clear upper harmonic lift
- Film harmony requiring directional but luminous tension
Play
Keep 3 and ♭7 clear, place ♯11 in a register that projects, and avoid crowding the middle. If needed, remove 5 first to make room for color tones.
Common voicings / omissions
Shell + (9, ♯11) is often more effective than full stacks. With bass support, rootless shapes can sound cleaner and more modern.
