A 100th Anniversary Guide to Theremin Music 

Source: Bandcamp Daily.

The year is 1920. At a government-run think tank in Petrograd, a brilliant young Soviet scientist harnesses the power of something called the “heterodyne beat frequency” to create a mysterious-looking, antennaed box that creates a high-pitched wail, which intensifies when his hands come closer to it. This might sound like the plot of some sci-fi film noir, but it’s the real-life origin story of the device that bears Professor Léon Theremin’s name. An electronic instrument that you play without touching would seem like the quintessential axe of the virtual era, but 2020 actually marks the theremin’s 100th birthday.
