Can frequencies and melodies influence the growth and formations of bacteria in the sewage? This question is explored by the Swedish artist Cecilia Jonsson in her project “Contemporary Diagram – Berlin,” initiated and organized by singuhr –projekte. During a project residency at the sewage research facility of the Berliner Wasserbetriebe in Berlin-Neukölln, she used eight experimental set-ups to study how bacteria respond to different sounds and music. The results of these experiments will be presented at the Schering Stiftung.
