The base single-ended prop
First, what this page is not about: toss juggling. This is dual-wielded club spinning, one club in each hand, gripped the whole time. Held that way, clubs are the base prop of the single-ended family. They're the easiest prop to explain the single-ended story with, and they're the core of Vulcan Tech Gospel, the framework The Kinetic Alphabet is built on. The lineage lives on the notation page.
Translating the alphabet from staves to clubs takes one sentence. Pretend you're holding a staff whose other end is invisible, or got cut off, and do everything exactly the way you would with the staff. A club's orientation is the staff's thumb orientation, and the rest follows: same grid, same letters, same timing, as the player beside this shows.
The two mandalas trace the identical sequence. In the staff render, both ends of each prop leave a path. In the club render, one does. Half the pattern is gone, and that missing half is where the single-ended vocabulary comes from. On a staff, an isolation and an extension are one motion, the thumb end isolating while the pinky end extends. A club can only do one at a time, so club spinners know them as two moves that look nothing alike despite identical underlying geometry. Antispin splits too: a club's antispin reads as a vertical or a horizontal flower depending on its orientation through the pattern, which is exactly what VTG's vertical antispin and horizontal antispin name. On a staff those distinctions fold away. The staff page tells that side.
