These photos were taken when we were still in Korea. We used to go to the park near the ocean and one fine afternoon, there were displays for some kind of a presentation out there.
Their traditional music instruments.
I don't know what they call those instruments but there is a kind of music instrument called zither that I read online. According to crosswordsolver.org, ZITHER is a musical instrument with string stretch over a flat sounding box, it is laid flat and played with a plectrum and with fingers. Below is an image I borrowed from britannica.com of a Korean lady playing Zither.
