You’re walking through a Japanese forest on the southern island of Kyushu. Among the trees you hear the sounds of bird song. A gentle breeze rustles the leaves. A melody you’ve heard before rings faintly through the air. What is that? Bach.

This magical experience is real, thanks to Creative Director Morihiro Harano and his team at Mori Inc.

In a collaboration with the carpenter Mitsuo Tsuda and sound engineer Kenjiro Matsuo, they made and placed an enormous xylophone that’s designed to play Jesu, Joy of Man’s Desiring—the final movement to Bach’s renowned cantata Herz und Mund und Tat und Leben.
