Starting formation - facing couples. The active or directed couple moves forward between the outside couple who sidesteps slightly to let them through then sidesteps back together again.
SPLIT TWO: Starting formation - a couple or tandem facing another couple. The active or directed couple or tandem moves forward between the inactive couple who sidestep slightly apart to let them through then sidestep back together again. The call is not complete until the next command tells the active dancers what to do next. From an 8 chain thru formation, an example usage would be CENTERS SPLIT TWO, AROUND 1 TO A LINE. Here, it is implied that the active dancers will SEPARATE, although other directional calling is sometimes used instead (e.g., CENTERS SPLIT TWO, BOTH TURN LEFT AND PROMENADE SINGLE FILE WHILE THE OTHERS ...).
STYLING: Men's arms in natural dance position; ladies may work skirts. The couple that is separated by the active couple simply moves out of the way so that the active couple may move between them. Once the active couple has moved through and is out of the way, the couple who separated will move together once again.
Timing: SS, heads or sides pass thru around one to a line, 8; around two to a line, 10; to home, 12. From a Box, insides split the outsides to a line, 4 steps; to home position, 6.
