Developing Intelligence

Mick Grierson has created a real-time EEG-based brain-computer interface for music synthesis. You can watch a video here.

We’ve been designing experiments to test how classic ERPs (P300/600, N400, etc) may emerge from user interactions with this system, given previous demonstrations that those waveforms are sensitive to the “grammar” and “meaning” of musical harmonies, respectively.

What waveforms would you look for in this system?

    Perhaps within the next hundred years, science will perfect a process of thought transference from composer to listener. The composer will sit alone on the concert stage and merely ‘think’ his idealized conception of his music. Instead of recordings of actual music sound, recordings will carry the brainwaves of the composer directly to the mind of the listener.

    He seems to be putting more mental effort into playing a scale than I, as a 49 year old with stiffening fingers, put into learning a five-part fugue! My first instinct as a smart but ignorant layman is that he’s using a completely different part of his brain to normal musical activity.

    @Kyle, Cool quote.

    @Ian, if you’re right I’m even more interested. Imagine music created by a previously “unheard” part of the brain!

    I think it’s pretty funny that Mick is effectively getting single-trial ERP data, where experts across the world only get reliable ERPs by averaging hundreds of trials. what’s that chinese quote… “The person who says it cannot be done should not interrupt the person doing it.”

  4. Interesting, but (without clicking on the links) it doesn’t indicate that the player in the video has any musical abilities without the computer. If the music demonstrated is strictly the result of him composing with no formal knowledge of music, it is amazingly awesome. I have had many musical ideas that I could not possibly play, even with the abilities I do have.
