About cascade

In toss juggling, a cascade is the simplest juggling pattern achievable with an odd number of props. The simplest juggling pattern is the three-ball cascade, This is therefore the first pattern that most jugglers learn. However, although the shower requires more speed and precision, "some people find that the movement comes naturally to them," and it may be the pattern learned first. "Balls or other props follow a horizontal figure-eight [or hourglass figure] pattern above the hands." In siteswap, each throw in a cascade is notated using the number of balls; thus a three ball cascade is "3".In the cascade, an object is always thrown from a position near the body's midline in an arc passing underneath the preceding throw and toward the other side of the body, where it is caught and transported again toward the body's midline for the next throw. As a result, the balls travel along the figure-eight path that is characteristic of the cascade.
