Bobby McFerrin wrote the song “Don’t Worry Be Happy” and in this talk he demonstrated how the brain can work. He begins by jumping in one place on the stage singing a pitch. He has the audience match this pitch. He then moves up and down giving the audience matching pitches until they finally figure it out. He then moves across the stage while the audience is singing the pitches, and he is improvising a melody over the top.
It is amazing that this could work. It just goes to show how innovative the human brain is. He only needed to give the audience a few pitches before they could figure it out on their own. It is also amazing that they could continue to sing the pitches while he was singing his own pitches over the top. Just another point about the human brain. It can focus on two things at once.
