Siteswap is a juggling notation used to describe or represent juggling patterns. It encodes the number of beats of each throw, which is related to their height, and the hand to which the throw is to be made: "The idea behind siteswap is to keep track of the order that balls are thrown and caught, and _only_ that."〔Knutson, Allen. "(Siteswap FAQ )", ''Juggling.org''.〕 It is an invaluable tool in determining which combinations of throws yield valid juggling patterns for a given number of objects, and has led to previously unknown patterns (such as 441). However, it does not describe body movements such as behind-the-back and under-the-leg. The numbers are as follows:〔"(Juggling by numbers: How notation revealed new tricks )", ''BBC.com'' (BBC article with explanatory video)〕 *0 = "missing"/rest (hand ) *1 = pass (hands ) *2 = hold (hand/no toss ) *3 = (3-ball) cascade toss (hands ) *4 = (4-ball) fountain toss (and into same hand ) *5 = high toss (hands ) For example, a three-ball cascade may be notated "3", while a shower may be notated "5 1".〔 The name ''siteswap'' comes from the ability to generate patterns from "swapping" numbers in preexisting patterns, such as 55500 and 50505 (or Flash and Snake). ==Origin== The notation was invented by Paul Klimek in Santa Cruz, California in 1981, and later developed by undergraduates Bruce "Boppo" Tiemann and the late Bengt Magnusson at the California Institute of Technology in 1985, and by Mike Day, mathematician Colin Wright, and mathematician Adam Chalcraft in Cambridge, England in 1985 (whence comes the alternative name). The numbers derive from the number of balls used in the most common juggling patterns. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「siteswap」の詳細全文を読む スポンサード リンク
