The
koto (
Japanese: ) is a traditional
Japanese stringed musical instrument originated from the
Chinese zheng, and similar to the
Mongolian yatga, the
Korean gayageum, and the
Vietnamese dàn tranh. The koto is the national instrument of Japan. Koto are about length, and made from
kiri wood (
Paulownia tomentosa). They have 13 strings that are strung over 13 movable
bridges along the width of the instrument, and there is also a
17-string koto variant. Players can adjust the string pitches by moving the white bridges before playing. To play the instrument, the strings are plucked using three finger picks, otherwise known as plectra (on thumb, index finger, and middle finger), to pluck the strings.
