Komorebi is a Japanese word that can be translated as “sunlight filtered by trees”. It refers to the shadow play that we find on the forest floor when going for a walk in the woods on a sunny day. The mystery of this image is that an apparently simple shadow play conceals in fact a great deal of complexity. The movement of winds, clouds and the sun, the patterns of growth in vegetation, are all living in this projection. This image suggests to us that “life” or “aliveness” is not an exclusive property of organic life forms, it is also a property of complex systems that go beyond individual organisms or biological life as we understand it. How can we translate this image into music?
