parade term. This means that each rank (line) of the band will split in half. The left half will move behind the right half, so that the band is only half as wide as it originally was. This is used at the end of a parade when going from a road to a sidewalk, or from a two-lane area to a one-lane, etc. For example, Before doubling back: F E D C B A (where A is the front-right) L K J I H G After doubling back: C B A F E D I H G L K J When there are an odd number of people in a row, the right side has the extra person: Before: E D C B A After: C B A-- E D The right side should never have a hole in it. (Lines should be justified right but I can't convince the computer to do that.) For more info about how and when to use it, see also: Parades.
