Quick Summary

The gaku-so is a Japanese musical instrument, specifically a long zither with movable bridges and typically 13 strings. It is played by plucking the strings with picks worn on the right hand, while the left hand is used to alter pitch or add ornamentation by manipulating the strings. This instrument is used in solo performances, chamber ensembles (often with shakuhachi and shamisen), and in gagaku, Japan's traditional court and religious music. The gaku-so is considered Japan's national instrument. It is also referred to as koto.12
