Facing Couples
Square Thru (1,2,3,4) is defined here; for Left Square Thru (1,2,3,4) see the comments below.
In what follows, "Face partner" means to make a 90-degree turn in place to face one’s current partner. Complete as many of these actions as appropriate:
Back-to-Back Couples
Square Thru 1: 2
Square Thru 2: 5
Square Thru 3: 7 or 8
Square Thru 4: 10
With the Pull By the hands are released as each dancer passes each other so as to avoid guiding one another to turn the wrong way.
As in Right and Left Grand, dancers should make their opposite hand available for their next Pull By (or the next call). On each Pull By, as dancers pass they should be facing Head or Side walls (unlike Right And Left Grand, which blends into a circle).
Left Square Thru (1,2,3,4) is similar to Square Thru (1,2,3,4) except that it is started with the left hand and hands are alternating thereafter; the word "Left" is required. E.g., Heads Lead Right, Circle To A Line, Left Square Thru 4, Left Allemande.
The Ocean Wave Rule applies to this call.
The movement can be continued beyond 4 hands (for example, Square Thru 5).
There are some alternative ways in which Square Thru can be called:
An extended application of Square Thru is "Square Thru, on the Third (or other) Hand..." where the Pull By action on the specified hand blends into the following call. For example:
Unless the caller specifies, the call "Square Thru, on the Third (or other) Hand" does not have a clear ending formation. Some believe it ends in facing couples, others in a wave. For this reason, the call that follows must be proper and have the same effect from both these formations; that is, the Facing Couples Rule or Ocean Wave Rule must apply. Historically Touch 1/4 and Left Touch 1/4 are exceptions that are considered proper, with the Pull By blending into the Touch:
The extended application Square Thru 1 1/2 (or 2 1/2, etc.) includes half of the next Pull By and ends in an Ocean Wave. Dancers are not expected to know this variation, so it should only be used following an appropriate workshop.
