C#11

— About this chord

C#11 (C# dominant 11th) leans on the suspended 4th/11th over a dominant 7th, giving it a quartal, open, slightly ambiguous color that's less about the major 3rd and more about stacked fourths. Common in funk and gospel comping where the 11th replaces or sits alongside the 3rd for a modern, unresolved vamp sound. Guitarists favor compact movable grips that omit the 3rd entirely.
