The brain’s predictable music

The EEG signal spectrum falls inside the human ear sound frequency range. If we translate these electrical signals to audio, we can listen to low frequency waves. This is our natural brain music.

We can analyze the interaction between  music and our EEG, the interaction between external music and our internal music. Several studies show that the complexity of the electroencephalogram increases when the brain processes music, and that our brain response has significant induced differences related with the frequency domain of the music. But is it possible to play our internal music together with other instruments?

Several compositors have tried to play music with EEG signals. We can find examples of primitive electroencephalogram systems connected to symphony drums, and more recent experiences that produce music coupling brains waves. We can pursue this amazing experience to create closed loops between the external music and our internals sound sources, but the music results are for the moment unpredictable.

Music need repeatability and control; we like listen our pieces several times, and we appreciate the differences between players, we recognize instrument virtuosity. Maybe in the future we will find brain instrument music virtuoso of a music feedback brain instrument.

Such a brain virtuoso will need full control over the instrument: only a powerful BCI connected to a sound generation system, and daily hard instrument practice will possibly produce a predictable Brain's music.
