The theremin is an electronic musical instrument invented in the 1920s by Léon Theremin. Its’ futuristic sound involve the manipulation of electromagnetic fields around two antennae. The instrument is played without physical contact and players control sounds by moving hands and fingers around the antenna to raise or lower the tone, and up or down over a looped antenna to control volume. “When you play the theremin, it looks kind of magical. Maybe even as if you could cast spells,” Carolina Eyck said in an interview with BBC Culture.
