Bartholomus Traubeck took thinly sliced tree truck rings and turned them into records that could be played on a modified record player. What you are hearing is the data recorded from the rings of this Austrian Ashe tree to the sound of the piano. The tune is eery and describes it's whole life. I think this is a pretty amazing project and such a beautiful way to give this tree a voice that perhaps, man might understand.
"A tree’s year rings are analysed for their strength, thickness and rate of growth. This data serves as basis for a generative process that outputs piano music. It is mapped to a scale which is again defined by the overall appearance of the wood (ranging from dark to light and from strong texture to light texture). The foundation for the music is certainly found in the defined ruleset of programming and hardware setup, but the data acquired from every tree interprets this ruleset very differently."
