Yugake has a shallow bump (tsurumakura, a part of a yugake glove to set a string) which is enough to set a string at the base of thumb, and they set a string this part and put the middle finger for mitsugake, or the annular finger for yotsugake on the tip of a thumb and add an appropriate twist to the wrist and then the string comes to be held.
ユガケの親指根には弦が引っかかる程度の浅い段差（弦枕）が付けられており、ここに弦を掛け、三ツガケは中指、四ツガケなら薬指を親指先に掛け、手首に適度な捻りを加える事により弦は保持される。
