So, we can say with certainty that music is not only a universal part of human culture, it also has a profound impact on us at the neurological level. For example, studies have found that children who have musical training are able to more accurately process sound, which can help with speech, literacy, and reading skills. And this is not to mention the long-term impact musical training has on the adult brain. Adults with musical training, even a moderate amount of 4-14 years, saw fewer degenerative effects of aging on the brain up to 40 years after they stopped playing.
