From a R-H Wave:     before Switch The Wave   after

From a L-H Wave:     before Switch The Wave   after

• From a R-H Wave, everyone moves to the Right;
  From a L-H Wave, everyone moves to the Left.
• Think about moving toward the handhold that you have with the adjacent dancer. You might even give that dancer a slight tug to get both of you moving toward the correct direction.
• At A2, Switch The Wave may only be called from a Wave. However, at C1, Switch The Line (same definition as Switch The Wave) may be done from any Line of 4.
• If you start as a Center, be sure to Run toward the nearest End position. Think about flipping away from the Center.
• Ends Cross Run to the far Center, passing each other in the process.
• Everyone can Roll after Switch The Wave.
• Switch The Wave can also be thought of as a Swing-Slither (except that everyone can Roll after a Switch The Wave, whereas those doing the Slither can not Roll).
