T-Bone is a name given to any (usually rectangular) setup in which at least one dancer's facing direction is 90 degrees off relative to another dancers' facing direction. The word 'T-Bone' is typically not said unless the caller wishes to emphasize that the dancers should pay attention.

When doing calls from T-Bone formations, do your part of the given call. Assume that dancers T-Boned to you are facing in whatever direction is necessary for you to do your part of the call. Usually, you will not interact much with those who are T-Boned to you, and the call may feel quite different than when done from a normal setup.

Examples of T-Bone formations:     In the last example, dancers act as if they are in Lines, and dancers act as if they are in Columns.

Acey Deucey 之前   之后
Out Roll Circulate 之前   之后

When executing Circulates (and calls involving Circulates) the Lead dancers who make a loop as part of their traffic pattern must move around the outside of any dancers who are moving straight ahead. This means that some dancers may pass Right-Shoulders while other dancers may pass Left-Shoulders. Be careful to pass the correct shoulder since the caller could fractionalize the call.

注意:

• When done from T-Bones, calls that normally end in Lines often end in Diamonds and vice-versa.
• Be very precise with your positioning when doing calls from T-Bones. Make sure your formations are compact and that you are directly lined up with a wall.
