Alpha Untitled is an immersive audio-visual installation based on alpha brainwave frequencies of 8–12Hz. Alpha waves are neural oscillations dominant in the brain during the state of deep meditation or the early stages of sleep. Alpha waves are associated with a healthy mind and a stress-free life. The combination of surround sound and visual projections is intended to encourage the visitor to experience a trance-like state. 

The approach to this project was intuitive and based on improvisation and performance. It consists of a 16min drone sound composition made up of three sustained tonal elements: bass, harmonics and binaural. The visuals, each corresponding to a different sound element, were generated using audio signals fed through custom built analog video hardware, then manipulated in real time and filmed live. 

To produce the precise frequency sound composition for this piece Tomas Jefanovas worked with sound artist Tasos Stamou, who is also a specialist in circuit bending & hardware hacking. Tomas used two of Tasos’s modified video effects machines in this project, as well as a 3trinsRGB video synthesiser and analogue video mixer.
