In 1939, a global conference in London forever changed the way we hear the world, standardizing musical pitch to A440Hz—a move some claim was spearheaded by Joseph Goebbels to induce mass aggression and vulnerability. This documentary explores the haunting intersection of acoustics and history, investigating whether the Nazis truly manipulated the fabric of music for psychological warfare. From the "ghostly" hallucinations caused by infrasound to the mesmerizing geometric patterns of cymatics, we dive deep into the science of vibration to uncover how sound shapes our bodies, our minds, and our very reality.
