An electroencephalophone or encephalophone is an experimental musical instrument and diagnostic tool which uses brain waves (measured in the same way as an EEG) to generate or modulate sounds.
In the summer of 1968 Kurenniemi visited an electroacoustic music conference organized by Teatro Comunale in Florence, Italy.
During the conference Kurenniemi was introduced to Manford L. Eaton’s ideas of biofeedback as a source of musical or composition material.
In the 1970s, David Rosenboom and Richard Teitelbaum used EEG based devices to enable performers to create sound and music with their brain waves.
Eduardo Reck Miranda is currently (~2004) involved in research which uses neural networks and brain interfaces to create music.
