They were hunter-gatherers, though unlike wolves, their lack of natural weaponry was offset by their increased brain function and rare status as not only tool users, but the first complex tool makers. For the proto-humans, the voice was a critical tool just as it is for the wolf.When the pack hunts, the members spread out across territory in search of prey.for which all vocal species seem to have expression, second back off or I will hurt you, and third come here.That third item is at a higher level of brain function in the concept of drawing friendly forces together for some reason.The oldest known recognizable instrument is a Cro-Magnon bone flute from 44-40,000 BC.However, ancient horn trumpets cannot be distinguished from other Pleistocene and Neolithic uses of animal horns.Soon, however, it would have been accepted as a new noise maker along with bones, stones and sticks.The trumpet is thus among the very oldest of musical instrument concepts.
(Rams horn Shofar from Microsoft Clip Art Library) When the population and technology of early Egypt reached the point of permanent settlements and non-agrarian occupations, the stage was set for the first imperialism.
One day, some proto-human was playing with the remnants of his food around the communal fire and happened across an animal horn with its tip broken off.
For whatever reason, demonstrating the curiosity that would facilitate the exploitation of the large cranial capacity of the genus, he blew on it like a trumpet and probably startled the pack into an alarmed state.
It appears that they engaged in percussive noise making as well utilizing available wood, stone and food by-products.
It is in this practice that the trumpet may originate.
