Juggling notation is the written depiction of concepts and practices in juggling. Toss juggling patterns have a reputation for being "easier done than said" – while it might be easy to learn a given maneuver and demonstrate it for others, it is often much harder to communicate the idea accurately using speech or plain text. To circumvent this problem, various numeric or diagram-based notation systems have been developed to facilitate communication of patterns or tricks between jugglers, as well the investigation and discovery of new patterns. A juggling notation system (based on music notation) was first proposed by Dave Storer in 1978 and while the first juggling diagram (a ladder diagram), by Claude Shannon around 1981, was not printed till 2010, the first printed diagram and second oldest notation system were proposed by Jeff Walker in 1982.〔Lewbel, Arthur (1996). "(The Academic Juggler: The Invention Of Juggling Notations )", ''Juggle.org''.〕 ==Diagram-based== While diagrams are the most visual and reader-friendly way to notate many juggling patterns, they rely on images, so are complicated to produce and unwieldy to share via text or speech. * Ladder diagrams - Each rung on the "ladder" represents a point in time (or "beat"). The juggled objects are represented as lines, their paths through time and between a pair of hands. * Causal diagrams - Similar to the ladder diagram but doesn't show the props held in a juggler's hands. Instead it only shows each "problem" — an incoming prop — and what the juggler should do to make space in his or her hands to catch that incoming prop. It is usually used for club passing and can be displayed or edited in some juggling software. *Mills Mess State Transition Diagrams - Mills Mess is a popular pattern in which the arms cross and uncross. Mills Mess State Transition Diagrams can be used to track these basic arm movements. 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「juggling notation」の詳細全文を読む スポンサード リンク
