Newly developed ground-breaking technology allows members of the Paramusical Ensemble to compose music.

Four musicians, who are severely physically disabled and unable to talk or move, are using cutting-edge technology to create music using just the power of their minds. The Paramusical Ensemble have worked with the University of Plymouth and the Royal Hospital for Neuro-Disability in the UK to develop the system, which allows for real-time composition of notated music.

Using ground-breaking computer technology, visual stimuli can be registered, processed and interpreted as a playable score. Short phrases of music are displayed on a screen next to a corresponding flashing light source. As a member of the Paramusical Ensemble looks at a particular light source, electrical impulses in the brain’s visual cortex are registered via an EEG cap, relaying the selected musical fragment to a display screen.

The system also allows the composer to control other aspects of the music, Dr Julian O’Kelly of the Royal Hospital for Neuro-Disability said in an interview with the BBC. “It also picks up the intensity of their focus,” O’Kelly explains. “It’s not just an on or off switch, they can control volume [dynamics]...
