The video shows a black and white image on a screen. The screen is split into four quadrants by white lines. In the center is a circular object, possibly a bell or gong, with intricate designs. Below it, text in Korean and English asks, "This beat phenomenon is the most distinctive feature of the bell's sound, but how does it arise?" In the lower right corner is a woman, also in black and white, wearing a turtleneck and performing sign language. The bottom of the screen shows more text in Korean and English: "The secret lies in the shape of the bell." The environment appears to be a museum or exhibition setting.
