The bar is a thin, horizontal stripe across the centre of the shield, usually in groups of two or three (any more and there would be confusion with barry, a treatment of horizontal lines of alternating colours). It is also possible to place decorative edges along bars, typically these are smaller than those found on the major ordinaries like the fess and pale, but have the same design and share the same meanings. Dancettee (sometimes spelled dancetty or dancy) is a bold, zig-zag pattern, perhaps the most distinctive of the patterned edges. Purists might argue that the French variant denché Is not the same, being of larger size and with the points being 90º, but there is much variation in actual practice so the difference is perhaps not that meaningful. Wade, quoting Guillim suggests that dancettee be attributed to mean water, in the same fashion as undy or wavy, and one can understand this allusion.
