A dominant seventh with a sharpened eleventh on top. Jazz players call this the Lydian dominant sound: the raised eleventh takes the edge off a plain dominant chord and leaves something brighter and more floating. It turns up over dominant chords that resolve down a half step, and over static vamps that never resolve at all.
