From a Generalized 2 x 4 (usually Parallel Lines), Generalized Thar, or other applicable formations.

As one movement, Circulate & Half Sashay.

起始于 R-H Two-Faced Lines:       Crossover Circulate 之前   半途时   之后
起始于 R-H Waves:       Crossover Circulate 之前   半途时   之后
起始于 Thar:     Crossover Circulate 之前   之后	起始于 T-Bone: (used only at C1 or above)     Crossover Circulate 之前   之后

Traffic patterns:

• From Parallel Two-Faced Lines: Leaders Tag The Line and Face In as Trailers Circulate and Half Sashay by having the Belles slide in front of the Beaus (i.e., do your part of Cross Trail Thru).
• From Parallel Waves: Leaders Trade (as in Trade The Wave) as Trailers Diagonal Pass Thru. Everybody passes right-shoulders. Ends in opposite-handed Waves.
• From Facing Lines: Pass Thru and Half Sashay (Cross Trail Thru).
• From Out-Facing Lines: Tag The Line and Face In.

注意:

• From Parallel Lines, Ends become Centers and Centers become Ends.
• Crossover Circulate can be done from any 2 x 4 Lines.
• The most common starting formation is Parallel Two-Faced Lines.
• From Parallel Two-Faced Lines, think of Crossover Circulate as a Circulate but exchange places with the dancer next to you as you go. Drop hands with adjacent dancers and move individually (don't move as a Couple). Trailers move forward, crossing from an End to a Center, without changing facing direction.
• The CALLERLAB definition of Crossover Circulate is described in terms of a diagrammed traffic pattern, and only allows the call to be done from Parallel Lines.

From Parallel Lines, there are two 4-dancer Circulate paths. When teaching Crossover Circulate, we often show these two paths by placing the Boys in one path, and the Girls in the other. Then we say Boys only Crossover Circulate or Girls only Crossover Circulate.

Crossover Circulate 之前   之后	Crossover Circulate 之前   之后
Crossover Circulate 之前   之后	Crossover Circulate 之前   之后

The realization that there are two Circulate paths helps some dancers to better visualize the call. Also, activating the dancers in only one of the two Circulate paths reinforces the idea that Ends become Centers and Centers become Ends.

Half Sashay [Basic]: From a Couple. Without changing your facing direction, exchange places by having the Belle sidestep in front of the Beau as the Beau sidestep behind the Belle. Ends in a Couple. From a Mini-Wave, do your part (i.e., from a L-H Mini-Wave, exchange places by sliding back-to-back; from a R-H Mini-Wave, exchange places by sliding nose-to-nose).

Trade Circulate [A2] (Holman Hudspeth): From applicable Parallel Lines (usually Waves or Two-Faced Lines). Leaders Trade (with each other) as Trailers Diagonal Pass Thru. From Parallel Waves only, Trade Circulate is identical to Crossover Circulate.

Cross By [C1] (Lee Kopman 1969): From Parallel Waves or a Thar. As one movement, 1/2 Circulate and Slide (nose-to-nose). A Thar ends in an opposite-handed Thar; Parallel Waves end in a Thar.
