grand piano, pyrocystis fusiformis, sea water 

A piano is placed in a darkened room. Positioned on its strings are transparent canisters. They are filled with sea water and monocellular algae (Pyrocystis Fusiformis). The toccata – developed by Sunlay Ameida Rodriguez and Andreas Greiner– is played on the instrument by the pianist. The plankton reacts to the music with the emission of natural blue light (bioluminescence).
