Music and movement go together in every human society: “music to my feet,” as it were. The human condition, particularly human emotional expression, is linked to music. Indeed, movement and a sense of time are intimately connected, and the brain is prepared to detect movement, both familiar and unfamiliar. Our sense of self is tied to movement. Aesthetic sense is a feature of the way we come prepared to interpret the world. Such aesthetics are historically variable and rich when the ecological conditions are suitable. Aesthetic judgment reflects our cognitive flexibility, and our extension and use of specific cognitive mechanisms to widen domains of human expression. Music evolved in the context of social contact and meaning. Music continues to allow us to reach out to others and expand our human experience toward and with others. This process began with sounds and expanded into song and instrumental music.
