Music is a common phenomenon that crosses all borders of nationality, race, and culture. A tool for arousing emotions and feelings, music is far more powerful than language. An increased interest in how the brain processes musical emotion can be attributed to the way in which it is described as a “language of emotion” across cultures. Be it within films, live orchestras, concerts or a simple home stereo, music can be so evocative and overwhelming that it can only be described as standing halfway between thought and phenomenon.

But why exactly does this experience of music distinctly transcend other sensory experiences? How is it able to evoke emotion in a way that is incomparable to any other sense?

Music can be thought of as a type of perceptual illusion, much the same way in which a collage is perceived. The brain imposes structure and order on a sequence of sounds that, in effect, creates an entirely new system of meaning. The appreciation of music is tied to the ability to process its underlying structure — the ability to predict what will occur next in the song. But this structure has to involve some level of the unexpected, or it becomes emotionally devoid.
