Description of the installation: It is an area inscribable in a circle with a diameter below 4 meters, wrapped in canvas supported by bamboo canes, pieces of wood, tufa or stone bases, tied with strings and ropes. The height, including the supporting structure, is of approx. 250 cm. Into the inside area, which can be accessed through special entrances, there are a carpet, camping mats and some cushions, in addition to the acoustic diffusers. . People can lie down on the mats and relax themselves. Furthermore, there are lighting devices which project light on the canvas.

Description of the audio part: It is a sound layer lasting approximately 60 minutes, which has been reproduced in loop. We recommended sessions of approximately 10 minutes. The composition is based on the use of binaural beats at Theta frequency (4-8 hz). Even if they are not audible and are perceived as vibrations in a binaural environment, those sounds have relaxing and therapeutic powers, and they stimulate the cerebral cortex. Since their pure sound is not particularly pleasant, the sounds are masked by natural sounds deriving from wooden and seaside environments, which, from a psychoacoustic point of view, are also relaxing. The composition is also overlapped by musical bases composed ad hoc and divided in 6 pieces of approx. 10 minutes, each interpreted by 6 different musicians. The audio has been reproduced in 3D-EST 8.0 thanks to one X-spat player, 6 Empire S-500 and two special speakers handmade by Massimo Liverani.
