Musical Tesla Coil
Published September 24, 2026
Musical Tesla Coil, also called Singing Tesla Coil, is a high-voltage plasma speaker that plays songs by modulating its spark output. Austin duo ArcAttack pioneered the format in 2005, and their 2007 South by Southwest debut kicked off a wave of YouTube performance videos that turned the coil into a hobbyist meme.
Overview
A Musical Tesla Coil is a solid-state Tesla coil rigged as a plasma speaker, where the pitch and rhythm of the audio track are baked directly into the timing of the electrical arcs1. Instead of a diaphragm pushing air, the spark itself heats and expands the air around it fast enough to produce audible tones, so the visible lightning and the music are literally the same signal2. The result is a performance object that reads as both a science demo and a live cover band.
Coverage on YouTube leans heavily into two flavors: theatrical live shows by ArcAttack, often with a performer inside a Faraday cage suit, and hobbyist bedroom or lab clips of hackers firing solo coils through video game themes3. Common set lists include the Super Mario Bros. theme, the 2001: A Space Odyssey intro, and rock and pop covers, which fit the coil's buzzy square-wave timbre4. The meme is less a joke format than a recurring genre of shareable science-spectacle videos that keep resurfacing whenever a new build goes viral.
