The work title “Chijikinkutsu” combines “geomagnetism” and “suikinkutsu (water-harp cave).” “Geomagnetism” is the Earth's magnetism, a force humans cannot feel although it is always present everywhere on Earth. However, compasses using geomagnetism were useful long before the Age of Discovery, and today are built into smartphones as electronic devices. Research has also examined geomagnetism's relationship to the behavior of migratory birds, honeybees, and certain bacteria. Beautiful auroras are also closely related to geomagnetism. In his book, the 16th-century scientist William Gilbert wrote that the magnetic Earth is like a living creature, but even today its principles have not been fully explained. The other element, “suikinkutsu,” has been an ornament in traditional Japanese gardens since the Edo period: a device for enjoying the resonant sound of water droplets falling into a buried jar near a washbasin. Since ancient times, Japanese people have had a distinctive sensibility that accepts sounds such as insects and wind in pine trees as nature as it is, and this delicate sensitivity gave rise to such devices. Just when I was making this work, I happened to visit a favorite temple in Kyoto. The temple stands in the most secluded part of the mountains. It has a garden with large Japanese white pines and a suikinkutsu in one corner. Hearing its sound, I felt that it resembled my work. Later, this expanded the work’s concept. The concept of this work of mine does not come from the positivism of science and technology on which media art depends, nor from the constructive Western musical theories underpinning some sound art. It is to incorporate the effects of geomagnetism, normally treated in science, and develop them into delicate sounds within the context of Japanese views of nature, creating a sound installation. It consists of several materials: water, sewing needles, glasses, and copper wire. Sewing needles float on water through surface tension; the needles, magnetized beforehand, point north through geomagnetism, and sound generated by current flowing through copper wire becomes audible. The system uses MIDI, with data sent from a music-sequencer application on an iPad distributed to each coil by a specially designed controller that supplies the current. I incorporate many elements into the work, and it is drawn by the magnetism and strikes the glass, producing sound. From the cups placed on the four sides of the exhibition space, rather than randomly, I sought to pare down the elements into a minimal expression. To consider what this minimality means, let us take taste as an example. In Japanese cuisine, “umami” is the most important taste, but until recently sweetness, sourness, saltiness, and bitterness were thought to be the four tastes. Much Western cooking has pursued depth of flavor by layering flavors, while Japan has taken a different approach, drawing out “umami” by using as few elements as possible. This is a pursuit of purity without extraneous flavors. Elements I did not add to this work include color, LED light, and sound amplification. As a result, the sound stood out and viewers could concentrate on it; it also led them to notice that the needles in the cups were related to geomagnetism. Because geomagnetism acts on a needle floating on the water's surface in a round cup, it resembles a small Earth. Minute sounds sharpen viewers' senses; the quieter the sound, the sharper the senses become. Gradually, sound feels internal rather than external. http://www.neloakamatsu.jp/chijikinkutsu.html
