From the T-Bone formation obtained from Facing Couples after one Couple does a turn 1/4 to face one another (1/4 In), or from other applicable formations.

Those who can Right Pull By and turn 1/4 to face the inactives (1/4 In);
all Finish a Square Thru n (i.e., Left Square Thru n - 1).

Ends in Back-to-Back Couples.

Split Square Thru:   Split Square Thru 之前         after Those Facing Right Pull By and turn 1/4 to face the inactives   Left Pull By 并做 1/4 In 之后   Right Pull By 并做 1/4 In 之后   Left Pull By 之后 (完成)

Split Square Thru 3:         Split Square Thru 3 之前   after Those Who Can Right Pull By and turn 1/4 to face the inactives   Left Pull By 并做 1/4 In 之后   Right Pull By 之后 (完成)

注意:

• If no number is given, assume n = 4.
• From a Squared Set, the designated dancers move into the middle, start the call, and finish with the inactive dancers.
• Alternate hands (right, left, right, left).
• As with Square Thru [Basic], each part of the call except for the last part consists of a Pull By and 1/4 In. The last part is a Pull By (without a 1/4 In).
• Dancers who are intially inactive start with the left-hand, and Square Thru one fewer hand than the given number.
• Callers sometimes use helper words such as 'Start A' or 'Begin A' when calling Split Square Thru (e.g., Boys Start A Split Square Thru 3). Technically, these extra words are not required.

Left Split Square Thru (n) [A1]: Start with the left hand.

Split Square Thru (n) To A Wave [C1]: Split Square Thru but on the last hand Step To A Wave. Ends in a Wave. If n is odd, the Wave is Right-handed; if n is even, the wave is Left-handed.

1/4 In [A1] (Jim Faulkenberry 并做 Clarence Watson 1959): From a Couple or Mini-Wave. Turn 90° in place toward the adjacent dancer. Ends in Facing Dancers.

Square Thru (n) [Basic] (Bill Hansen 1957): From Facing Couples (or a R-H Wave). Right Pull By and 1/4 In; Left Pull By and 1/4 In; Right Pull By and 1/4 In; Left Pull By. Ends in Back-to-Back Couples. If a number is given (e.g., Square Thru 2; Square Thru 3/4; where 1/2 = 2 hands, and 3/4 = 3 hands), then pull by that many hands, but do not 1/4 In after the last hand.

Split Square Chain Thru [A2]: 起始队形为可适用的 T-Bone 2 x 2, 或其他可适用的队形. 可以做的舞者做 Right Pull By, 然后转向未做动作的舞者; 所有人做 Left Swing Thru; Left Turn Thru. 结束队形为 Back-to-Back Couples.

Split [Square Thru] Concept [C1]: From a T-Bone setup. Those facing (or those in a R-H Mini-Wave) Right Pull By and turn 1/4 to face the inactive dancers; all Finish the given call. For example, Split Dixie Style To A Wave: those who can Right Pull By and turn 1/4 to face the inactives; all Left Touch 1/4.
