The mighty kauri trees of New Zealand face extinction. Kauri dieback, an infectious soil-borne organism that hitches a lift on bushwalker’s shoes is rapidly killing these native giants. But, they’re dying silently, which means the epidemic is overlooked. An infected kauri weeps gum in an attempt to wall off the disease – this is the tree silently crying for help. We needed to help these cries be heard, so we developed unique software, which transposed one kauri’s ‘tears’ into musical notation. This notation was performed by orchestra members, and the kauri’s pain was brought to life.
