› The Brain Is a Prediction Machine, and Music Reveals How It Works29/Sep/2021
There is not much evidence for how our brains perceive and decide when ‘something’ – be it a sentence, conversation or piece of music – begins and ends, but a research project from Aarhus University now sheds new light on the role of the brain as a prediction machine.
This comes from a scientific study in which Assistant Professor and AIAS fellow Niels Chr. Hansen documents that research participants experience so-called musical phrases – which correspond to a sentence or ‘unit of meaning’ – as complete and concluded, just as a phrase ends with a tone that creates uncertainty about what is going to happen next. In this way, the brain can effectively save completed phrases in its memory so that it is ready again before a new phrase begins.
The brain is one step ahead and matches expectations.
