An "Allemande Thar" (also known as a "Thar") is the name of a square dance formation. It consists of two criss-crossing Waves. (A Wave is a 4-dancer formation consisting of 4 dancers in a 1x4 line, holding hands, in which adjacent dancers are facing opposite directions).

For example, please look at the pictures on page http://www.ceder.net/def/crossby.php?language=usa&level=c1. The 2nd thru 4th diagrams are Thar-formations. In particular, the 4th picture, in which the Boys (squares) are in the center, and the Girls (circles) are on the outside, and everyone has left-hands joined, is more indicative of what is meant by most callers when they think of an "Allemande Thar".

The words "Allemande Thar" are also used directionally in calls.

For example,

• Allemande Left hang on make an Allemande Thar
  1. Face your corner if necessary;
  2. Left-forearm turn 1/2 way or more and hang on;
  3. Boys connect their right-forearms in the center to form a star.
• Allemande Left go forward two to an Allamenade Thar
  1. Face your corner if necessary;
  2. Left-forearm turn 1/2 way;
  3. Drop hands and step forward to end back-to-back with your corner;
  4. Right-handshake pull by with the next dancer to end back-to-back with them;
  5. Left-forearm turn 1/2 way with the next dancer but hang on this time;
  6. The new centermost dancers connect their right-forearms in the center to form a star.
