Through the magic of capacitive coupling. Video signal gets sent to CRT, CRT blasts electrons at the screen, blah blah, what happens?? CRISPY FUZZY GLASS. That shit is loaded with electrons. Guess what conducts electricity? YOU MOTHERFUCKER. So what happens when you strap a guitar pickup to your leg or arm or dick and put your hand near a source of electricity?
BSZZZZZZTT. Change the color or shape or brightness of the image on the screen and the amount the beam sweeps across the glass changes. Do that a bunch of times (a really colorful image like the outer ones) and you get weird tones! Do it consistently (like the middle one) and you get more stable ones! But they all have that 50/60 Hz base frequency. You can still hear the low hum with every sound he plays.
