Abstract
The hypothesized brain evolution and preconditions for language may have allowed for the emergence of musicality either simultaneously with or before the emergence of language. Music and language are parallel in their hierarchical, temporally organized structure, and the evolution of hierarchical representation in hominids may have provided the basis for musical representation. Because music could have been produced manually or vocally before the production of spoken language, it remains possible that language emerged from music and that music thus served as a communicative precursor to language.
