423

423 is the easiest symmetrical 3 object siteswap besides the basic pattern. The throwing rhythm is right-pause-right-left-pause-left... with a 1-beat pause between throws with the same hand.
Two balls are thrown with non-crossing throws like the throws in a 4 ball fountain (4s), one staying on each side of the pattern, and the other ball is thrown across from hand to hand (3s), about half the height of the non-crossing throws. The 2 is a pause between a 4 and a 3 with the same hand, where the other hand is just holding a ball and not throwing.

Some of the siteswaps listed below are shortened to leave out parts where you’re not doing anything. Click on them to see animations of the exercises.
You should practice doing these starting with your right hand and with your left hand, so that you will be ready to learn the full symmetrical pattern.

The non-crossing throws can be thrown on the inside of the pattern, going under the crossing throws, or they can stay on the outside of the pattern all the time, making a columns pattern.
(4,2)(4x,2)* is a slightly different way of doing this pattern, where all the throws are the same height and the rhythm is even: right-right-left-left-right-right-left-left...
