Here are two new sheets of tick notation for drumming class: the rhythmic framework (now with 2, 3, 4, 6, and 8 subdivisions, including the four variations of 3 and the two variations of 6), and Kpanlogo (three bell parts, shaker, clap, and three drum parts).
The Kpanlogo sheet introduces some new symbols for various drum sounds.
Because the main stick sound is a hit to the center and the main hand sound is a bounce of all four fingers at the edge, and these two sound approximately the same, both of these are represented with a simple vertical tick. A light tap is a small tick. For other sounds, the general idea is that symbols near the centerline are struck at the center of the drum, and symbols away from the centerline are struck at the edge of the drum.
It seemed logical to me that a press should be a horizontal line. A hand bounce in the middle of the drum is a deep, rounded sound, so the symbol is a round hump sitting on the centerline. A hand slap at the edge of the drum is a sharp sound, so the symbol is a pointy chevron away from the centerline.
