“Years”: Playing wood’s year rings

“Years” is an artwork created by Bartholomäus Traubeck that translates wood’s year rings into sound. The record player uses a system  that analyse tree’s years for their strength, thickness and rate of growth. This data are mapped to a scale defined by the overall appearance of the wood and serves as basis for a generative process that outputs piano music. The system is composed by arduino, ps eye, stepper ...
