Creative Director Morihiro Harano and his team at Mori Inc. have created a huge wooden xylophone in a Japanese forest that plays Jesu, Joy of Man’s Desiring—the final movement to Bach’s renowned cantata Herz und Mund und Tat und Leben. The xylophone is made of hundreds of pieces of different-sized wood; each panel along its length makes a different sound when it’s struck by a cascading wooden ball placed at the top of instrument. The video is stunning.
