Peter Larsen takes large, complicated sets of data, gathered from his study of how microbial populations interact with their environment, and turns them into music. In the piece you’re hearing here, different melodies represent different groups of microbes, playing as their abundance changes throughout the year. The chords and key are determined by the environmental conditions at this particular site, in the western part of the English Channel.
Life is jazzy.
