Notational Synthesis is a brain computer interface (BCI) for turning a persons mental state into music and visualizations
The data from the mind can be used to perform and create musical data for audio software or hardware. What do brainwaves sound like and can they be used to create music? This was the reasoning behind notational synthesis. There is another component that is a generative visual system to turn the sound generated from Notational Synthesis into images, colors, position and time.
