About “Voice of the stone”

“Voice of the stone” is a piece of artwork which plays a sound when someone touches the stones.
We made this piece with a local junior high student for the our exhibition at The Chigasaki City Museum of Art in 2016.The stones were chosen for their sensibility at a local shore. We held a workshop “How can I hear the stone’s voice?” and produced it together with electronic work and physical computing.

Why did you chose that stone?


Let’s try soldering.


This artwork uses the principle of the capacitive touch sensor. At first, we put copper foil tape on the back of the stone to accumulate electricity. The tone sounds from the stone by detecting a change in the quantity of electricity.

We made the tone of the stone from the wave pattern on the computer. We assigned a musical scale one by one of our impression of The student’s situation.


Background of the artwork

We are art units producing the art object and installation using electricity, light, and sound.We usually use the electronic circuit and wood for the artwork, but we used the stone of nature for the first time.
Because there are so many stones in the shore!

We wanted to watch it how does the person choose an answer from much information through making the artwork.

Today, We obtained much information and be able to connected through a network easily by improvement of the information and communication technology. However, We thought that we had to think about such a thing. What is our aim after gather information? How can we make good relationship with information? Will it be happiness?

the splendor of tactile

In a research for the artwork, We met the person who is able to finds a monkey easily in a forest. He was familiar with the forest and found a monkey in a forest like a doing netsurf. We also checked the ability to hear the voice of the stone by the native american.

Technique called “the trucker” in pursuit of an animal and a person

Because we thought that it might be possible to find something in the forest in this information society in the same way. There was wonderful information that they got from tactile sensation.

The touching is not only confirms the things,
At the same time, it will tell me how we feel.

We felt that the sensitivity that people choose something is important. We call the ability to see something invisible as “sensibility”. Through “touching”, we wanted to create works that evoke sensitivity and empathy.

Go out from the museum

We were touched by the fact that a strange link was created between junior high school students and stones. They were able to intuitively distinguish their chosen stone from afar. They may be able to talk to the stone that their sensitivity chose. There were a lot of visitors of museum who thought that stones could sing and people who wanted to touch various things around us. Perhaps they are creating sounds and lights in the body and the brain.

Every piece of information around the world is waiting for people to be found by new feelings.
