Our most basic social interactions
: Tomlinson, Gary. A Million Years of Music: The Emergence of Human Modernity. New York: Zone Books, 2015. In this fascinating and complex book, Tomlinson proposes that music emerged as hominids created the Acheulean biface hand axe some 1.8 million years ago in East Africa, a tool that was vital to hunting, carving carcasses, digging, cutting wood, and defense. Archaeological evidence reveals that the individual production of these axes required a sequence of six to eight specific physical actions. Our hominid predecessors likely made these axes in groups, synchronizing their bodily actions through gesture and sound. Associations between sounds—grunts, groans, and even oohs and aahs at a truly symmetrical axe and whoas upon seeing others’ efforts—and specific outcomes in the knapping of the stone into an axe were common. From this, Tomlinson suggests, tool makers learned the basic cognitive architecture of music: that different sounds signify different actions and different outcomes in the world, and that variations in sounds fit within a larger system of people making sounds together.GO TO NOTE REFERENCE IN TEXT
