Definitions of Square Dance Calls and Concepts
Ripple (The Line | Wave) | {n} [C2]

From a Line or Alamo Ring.

Designated dancers, working toward the Center of the Line, successively do a Partner Trade with each dancer until reaching the far end of the Line. Ripple n means to Trade with a total of n dancers. n can include a fraction (e.g., Ripple 2 & 1/2 means to Partner Trade with 2 successive dancers and then 1/2 Partner Trade with the third dancer).

Notes:
• When Ripple is called from a 1 x 8 Line, work on each side unless otherwise specified. Note however that a call such as Very Ends Ripple {n} where n is greater than 3 forces the designated dancers to cross the Very Center and work with dancers from the other side.
• The caller can specify the direction toward which the designated dancers are to begin (e.g., Head Lady Right Ripple 2). From an Alamo Ring, the direction must always be specified.
• If no direction is specified, the designated dancers do the first Trade moving toward the Center of the Line.
• There may be more than one designated dancer. For example, from a Wave, the call could be Ends Ripple 2.
