Static tone agent is an electronic musical instrument controlled without physical contact by the performer. It was made by inspiring from the first touchless electronic musical instrument Theremin, where the electrical capacity of the human body affects an electromagnetic field. Static tone agent uses the charges of static electricity to produce sound.
Static electricity is in an imbalance in the amount of positive and negative charges within the surface of an object.
Static electricity can be generated through Tribocharging, the separation of electric charges that occurs when two materials are brought into contact and then separated. Friction between two materials results in Tribocharging, thus creating a difference of electrical potential that can lead to an electrostatic discharge event.
On top of the musical instrument is located the antenna which reacts on the objects that were previously positively charged with the static electricity. By moving the object in the near from the antenna the rhythm of the sound can be controlled. On the bottom on the left and right legs of the body are located two light sensors. By closing and opening them the pitch of the sound can be controlled.
