First of all, you need to distinguish between the belt of the drum and the belt that is used to tie the drum around your waist, then hang the belt around your neck and put your left arm into it, so that the drum is carried diagonally over your right shoulder. At this point, check whether the drum is at the waist area, if it is on the upper or lower side, you need to adjust the length of the strap. When the length is suitable, then the two belts tied up, the belt should not be too tight, nor too loose, pay attention to make a live knot. The knot can be demonstrated to the students first, and then let the students tie the knot accordingly (see illustration a for the knot tying method). Finally, the drum should be rotated appropriately, and the drum should be placed on the left side of the body in front of the body, which is equivalent to the left side of the abdomen.
In order for students to master it well, you can let them tie the waist drum on their backs, untie it, and then tie it on their backs again, with the teacher checking and guiding them, and the students learning from each other at the same time.
