The oldest musical instrument that has been found is a flute from 35,000 years ago, and whoever built or played it was a member of our same species. We have no news that the other human species knew the music, although perhaps they delighted in the songs of the birds. But did they talk? What connection is there between language and music? It is a difficult question to answer because in the words and the musical notes the wind takes them.
