Numeric notation systems are more popular and standardized than diagram-based notations. They are used extensively in both a written form and in normal conversations among jugglers. Siteswap is by far the most common juggling notation. Various heights of throw, considered to take specific "beats" of time to complete, are assigned a relative number. From those, a pattern is conveyed as a sequence of numbers, such as "3", "744", or "97531". Those examples are for two hands making alternating or "asynchronous" throws, and often called "vanilla siteswap". For showing patterns in which both hands throw at the same time, there are other notating conventions for synchronous siteswap. There is also "multiplex siteswap" for patterns where one hand holds or throws two or more balls on the same beat. Other extensions to siteswap have been developed, including passing siteswap, Multi-Hand Notation (MHN), and General Siteswap (GS). Organizations  Resources  Other
