Humans learn a form of musical grammar. This parallels the way in which they learn to speak their own culture’s language. By middle childhood, it is already more difficult to become fluent in the musical tradition of another culture. It is still possible to learn to appreciate new genres of music in adulthood. However, the basic structural elements of one’s own culture’s music becomes incorporated into the wiring of the brain when you listen to music at the youngest ages. (Sternberg, Barbara, PhD.
