This paper presents a new spherical shaped capacitive sensor device for creating interactive compositions and embodied user experiences inside of a periphonic, 3D sound space. The Somatic Sound project is here presented as a) technological innovative musical instrument, and b) an experiential art installation. One of the main research foci is to explore embodied experiences through moving, interactive and somatic sound. The term somatic is here understood and used as in relating to the body in a physical, holistic and immersive manner.
