How does this even work? I’m really confused. Essentially, these are two Tesla coils sending out signals based on MIDI input. But how do you control the frequency of the shock to make the music? There are no speakers involved. Engineers? A little help?

Not sure how much this helps, but:
“The primary runs at its resonant frequency in the 41 KHz range, and is modulated from the control unit in order to generate the tones you hear.”

Basically the signal is sent through a filter which turns a switch on or off every time the wave crosses zero ( think of a sine wave). So a 44 KHz signal would cause the tesla coil to switch on and off 44 thousand times a second. I saw a video of this a while back, and that seemed to be the gist of how it worked.
Here’s a link to that video:
