Shamisen with thinner itomaki (tuning pegs) can be difficult to turn. In the beginning, turning the thin itomaki with only one hand can be challenging, especially on a chair. Without experience, this may even lead to the itomaki snapping or slipping out of the hole.
Rather, it’s much safer and comfortable to set the dou (body) on the floor and use two hands to carefully turn the itomaki.
