This composition is being performed with a Brain-Computer Music Interface using brain waves to control the music. The system uses an EEG machine and a technique called SSVEP. This allows a user to select commands by looking at one of 4 icons on a computer screen which are flashing at different speeds. The more the user concentrates their gaze on an icon the higher the brain signal reading for that command becomes. In turn the signal is fedback to the icons to provide some visual feedback to the user.

The icons are mapped to musical parameters and commands relative to the composition. Through 'playing' the icons the system becomes an instrument. By ordering, timing, and sequencing how icons are played, the whole piece is controlled from the triggering of sounds and arrangement of sections, to individual parameters of synthesis and effects.

As with performing with acoustic musical instruments there are some obvious mistakes, which add to the human element of performance. It's all played from memory and took a fair bit of practice. There's some odd interference from the desk over the beginning section which I might try and remove later on.
