2 juggler half-synchronous siteswap

This is a form of siteswap for two jugglers and describes a lot of "classical" patterns. 4-count, 3-count,… but also 7-club 2-count.

Typical Throws (with Clubs)

All throws with yourself just like 1-person siteswaps, all passes get a "p" appended:

Siteswap Name Abbr. 0 empty hand 0 1 zip z 2 hold or flip F 3 self S 4 heff H

Siteswap Name Abbr. 2p Zap Z 3p single pass S 4p double pass DP 5p triple pass TP

(Small/Capital z for zip and Zap can be used in patterns that have both throws - if only one type of throw occurs in the pattern, capitalization is probably not so far used consistently in the wiki)

Explanation

Basically every pattern in which both of two jugglers do e.g. straight single passes is at least half-synchronous. For asynchronous patterns, one person throws straight, the other diagonal for the same type of throw.

Remark: this should at least give one example using a Siteswap-diagram (also called ladder diagram)

4-count can be written like this:

A: 3p  3  3  3  3p 3  3  3 
B: 3p  3  3  3  3p 3  3  3 

I will additionally mark the beat 3 beats after the pass,in which the passes arrive with a "*":

    R  L  R  L  R  L  R  L
A: 3p  3  3  3* 3p 3  3  3* 
B: 3p  3  3  3* 3p 3  3  3* 

Now we can again "swap sites" between the pass of A and its preceding self and we get:

    R  L  R  L  R  L  R  L
A: 3p  3  3  4p* 2  3  3  3*
B: 3p  3  3  3*  3p 3  3  3* 

the 4p arrives at the same time as the 3p would and the pattern of B continues as if nothing had changed.

We can change the same pattern further in the throws that stay with A, e.g.:

    R  L  R  L  R  L  R  L
A: 3p  3  3  4p* 4  1  3  3*
B: 3p  3  3  3*  3p 3  3  3* 

There is one obvious exception - A cannot do a throw that would arrive at the time when B's pass arrives.
