Eo (hangul: ?; hanja: ?) is a wooden percussion instrument carved in the shape of a tiger with a serrated back, played by running a bamboo whisk across it to mark the ends of sections. Its name is derived from the Chinese y?. On the back of the tiger is a Jeo-eo(??(??)) that looks like 27 saws. When the music stops, the performer knocks and scratches this Jeo-eo(??(??)) through the Jin(?) and gives a signal.
