Yuto Hasebe is a Japanese artist who is interested in the relationship between nature and musical expression. He creates the series of string instruments inspired by the shape and the material in nature. In early practice, he created the string instrument "Tree Guitar" has a branching structure. At first glance, the string's length was irregular but the strings were setup according to its natural structure. He made performance along with the environmental sounds recorded in the forest.

His recent work "Deer Calling" is the cello-typed instrument made out of deer antlers that was given from a hunter. And he gave a performance with it at huge park that was a former hunting ground in Prague, Czech Republic.​

About an environmental problem in Japan, the beast harm by wild deer is one of the topics. They eat crops,  fallen leaves and soft tree bark in the forest which caused to annoy people, soil can not grow fertile and trees will wither. These all things are in danger of breaking natural ecosystem. Now, the number of wild deer are increasing. Therefore, local hunters and city governments are destroying wild deer to extermination. On the other hand, in Japan, deer are often respected as a god' messenger. I feel a contradiction about value of life here. I thought that if I used a deer antler as material for the instrument, it would become music expression for value of animal's life.
