PlantsPlay detects microfluctuations in conductivity between two points on a plant. This conductivity is largely influenced by the amount of water between these points, which fluctuates as plants photosynthesize and move chloroplasts. These variations are graphed over time, creating a wave that is then translated into pitch. These pitch signals are used to control specially designed instruments. Each note you hear reflects a real-time change within the plant. The larger the gap between consecutive notes, the more significant the change occurring within the plant.
