Performance – them musical brain
What began as a welcome distraction from his slow recovery from surgery became an exercise in data representation. Ulf Schöneberg himself was not musical but was inspired by conversations with his musician’s son to see if the data could be converted into music. He developed software to create music based on an algorithm made up of Irish folk melodies. While the algorithm provides the musical material, the EEG data influences the generation. “It reacts to different frequencies of brain waves, so you can do some things to change the music,” he explains. “Open or close your eyes, concentrate on something – it affects things like tempo, volume, and timbre.” The software also creates a real-time visualization of brainwave frequencies and locations; an aesthetic representation of the data in crossed lines and colors reminiscent of an animated Kandinsky painting.
