Saturday's Sónar by Day will kick off at Stage+D with a unique experience. The public will be invited  to enter an immersive soundscape, designed to induce a deep state of relaxation, based on principles scientifically backed by research into the circadian rhythm. This landscape is created by Endel AI, an Artificial Intelligence that uses James Blake's vocals and music, which are adapted to the exact location of the installation, the weather, the time of day and even exposure to sunlight. The sound will be accompanied by visual works also developed by Endel AI. Psychoacoustic principles such as pure intonation and sound masking help stimulate the parasympathetic nervous system, encouraging relaxation. Stage+D can enter, exit, walk, sit or even stretch out in the space, enjoying an experience that is adaptive and unrepeatable.
