Sound sleep: Lullabies as a test case for the neurobiological effects of music.

ABSTRACT

Music is part of the cultural practice and, at the same time, is interwoven with biology through its effects on the brain and its likely evolutionary origin. Studies on music, however, are traditionally based on the humanities and often carried out in a purely historical context, without much input from neuroscience and biology. Here, we argue that lullabies are a particularly suited test case to study the biological versus cultural aspects of music.
