The Takeaway
Music is often viewed as a purely cultural invention that varies wildly across history and geography. This research identifies an ancient evolutionary calculus of energy and surprise that has remained constant across species for millions of years. This specific signal pattern appears in the vocalizations of animals and the structure of modern professional singing to ensure the listener cannot look away. The brain is hard-wired to respond to these specific rhythmic and tonal shifts regardless of musical taste or training. This means that a hit record and a predator's warning call are both using the same biological exploit to dominate human attention.
From the abstract
What is in a song? Although the evolution of music has been subject to philosophical and scientific study, the exact mechanism(s) of fitness signaled through the quality of music has not. As music and dance functionally aim to hold an observers attention, we investigate the features of sound that stimulate attentive behavior in an audience. We propose a calculus of audiovisual attention to determine an individuals f(x) = Control=position, f(x) = Energy=change in position and f"(x)=Surprise=chang
