Korean dadeumi cloth pounding: two smooth wooden paddles beat folded white ramie cloth on a flat granite stone in a hanok room, soft daylight coming through hanji-papered doors. A brass bowl of water sits on the floor right beside the stone. With every strike, concentric rings shiver outward across the water in the bowl, timed exactly with the beats; between strikes the water stills. Four strikes in a steady rhythm, then the paddles rest on the cloth. Only hands and the sleeves of a white hanbok jeogori visible, no faces. Korean tradition, not Japanese or Chinese. Static locked-off camera. Sound: a crisp wooden tok-tok rhythm, no speech. No text, no letters
