This pattern is called (4,4). When we use synchronous notation, we still mark everything as though it were alternating hands. The hands still alternate as we write them, we’re just lumping them together into the same beat: (Right, Left)
Here’s another example – (6,4)
In this pattern, nothing crosses. The right hand only juggles 6s and the left hand only juggles 4s. How do we know how many objects this pattern is for? The brackets are confusing, but don’t let that fool you – the method we used for the asynchronous patterns works here, too:
6+4 = 10
10/2 = 5
This is a valid pattern for five balls.
In (6,4), the right hand juggles three balls (thrown at height 6) and the left hand juggles two balls (thrown at height 4.) Simple as that!
But what if we want to get the balls to cross? Let’s look at a classic, more complicated five-object pattern:
…what does that x mean?
Since we’re lumping two throws into a single beat, we can’t have odd-numbered throws in a pattern. There’s an excruciatingly nuanced explanation for this. To sum it up, when you have an odd numbered throw in a synchronous pattern, there’s nowhere for the object to land (from the perspective of notation, at least,) since we’re bundling beats together. In order to mark the idea of a crossing throw, we stick an x behind it. If we didn’t, or so I’m told, the space time continuum would cease to exist. (…and if that happens, it’s all your fault!)
