Apparently the first form of verbal communication between human beings closely approximated what we might define as a “song,” i.e., the verbal utterance of sounds bound together by a communicative, or emotional, structure. In short, our ancestors talked to one another by using sounds formed by a logic dictated by their feelings or needs at a given time. It’s no coincidence that our voice is known as the “first instrument,” the first means of emitting sounds that were elaborate and pleasing (or displeasing, depending on the case).
