The Hook: In previous sessions, we touched on the origins of music in Australian penal colonies (the 1830s), but that’s a human story. Yet if you dig to the root—why did people even start "singing" or "making sounds" in enclosed spaces? Research into the acoustics of prehistoric caves suggests our ancestors used the natural resonance of stone as an instrument. This is the direct antithesis of modern digital studio sound processing.
The Investigation: Archaeoacoustics is the discipline that studies how the physical parameters of ancient spaces influenced human behavior. Research (for example, in Paleolithic caves) shows that the deepest, hardest-to-reach spots with cave paintings often have the best acoustic properties—resonance. People literally chose ritual sites based on how their voices echoed off the walls. This wasn’t just "singing in the shower"—it was the creation of a full sensory environment where sound and visual art fused into a single, powerful cognitive experience. Unlike modern studios, where we strive for control over the environment, in caves, ancient humans submitted to the architecture of nature itself.
Findings: This shifts our view of the "primitiveness" of Stone Age culture. They weren’t just "drawing"—they were designing acoustic theaters, using resonance as a technology to influence the psyche. It makes you wonder: isn’t modern concert hall architecture just a pale imitation of what nature offered us thousands of years ago? We’re still dependent on the physics of space, even as we try to replace it with processors.
