A design of space, shape, form, time, or energy which is the same on either side of a dividing line or plane. The quality of a dance work resulting from the artist's technique and compositional elements in distinct relationships of contrast or harmony. A coherent entity with all parts having a harmonious relationship that contribute to the sense of completeness. A sharp, quick action done by moving body parts quickly back and forth or side to side. The speed of the shaking can be changed slightly but if done too slowly the vibratory quality is lost.
Body parts can shake separately or simultaneously.
