Oh, and it also speaks English.
Shout out to Sheet Music Boss. Go check out and sub to their channel!- / @sheetmusicboss
Also go check out Grant from 3Blue1Brown. He the best explainer of complicated stuff I know (the buttery smooth delivery certainly doesn’t hurt)- www.3blue1brown.com/
Cool piano animation by Jared Owen- / jaredowen
Finally, the piano in the video is from Edelweiss. Thanks to our friends at pianodisc.com/ for helping to modify one of their Prodigy player systems to make this possible. We had to modify it so it could play Rush E and all the keys at once otherwise out of the box they can play about 30 keys at once. If you want more info, you can find it here- www.edelweissinfo.com/
P.S. No Chopstix were hurt in the filming of this video (i.e. he didn’t ACTUALLY catch fire).
I started a company called CrunchLabs where we build a toy together and then I teach you all the juicy physics for how it works. So if you want to learn to think like an engineer and have really fun time doing it, check out the current promotion where you get 2 FREE boxes at crunchlabs.com
You should also go subscribe to the CrunchLabs KZhead channel cause we’ve got some bangers in the pipeline- / crunchlabs
Thanks to these folks for providing some of the music in the video:

  • Thanks to Sheet Music Boss and Grant and Chopstix!! Sorry it’s been a hot minute since I’ve uploaded but I promise I’ve been working harder than ever planting and cultivating some seeds that should bear some very delicious fruit for all of you over the next 5 months or so.

  • The part about how when it gets chaotic and some sounds are more or less muted is because the piano can't reset its hammers fast enough before the next note is played. That's why Rush E is strictly electronic. If you did play it fast enough, the piano wouldn't be able to keep up.

One note though, the "backstop" is actually not for repetition, it's to prevent the hammer from bouncing off the rest and striking the string again.

  • The dampener on each string also does ONE MORE THING: Prevents harmonic vibrations from vibrating related strings. There are things called overtones when a note is played. You don't just get that note, but you get other, higher notes as well because of how the period of the string's vibration can be split into other notes. And, if you hit the harmonic resonance, things vibrate. So, a lower note could cause strings of higher notes with relative periods to vibrate as well... if they didn't have a big, fat felt pad on them. This is also why some intervals in a scale sound better than others.

    • @@anonymous.dontask.8343 not quite. The effect he’s talking about isn’t based on proximity. He’s talking about resonance and harmonics. Where if you play a low C, another string at middle and high C will vibrate slightly despite being entire scales away in terms of distance on the piano, and has a lesser effect for certain intervals in between. Has something to do with the frequency of vibration, which I don’t know in detail since I don’t study music theory or physics. Being based on it just being close would imply it’s just the impact of the hammer bleeding over to other notes, which probably would still happen, but that’s not what is being discussed.

    • It's actually often overlooked in how modern music theory is taught. The average general music theory class will usually cover harmony, melody, and maybe some basic rhythm, completely brushing instrumentation and timbre despite timbre being one of the most complex and interesting aspects of music. It's why Beethoven's 5th sounds weird on a synthesizer and why All Star by Smash Mouth sounds out of place when played by an orchestra. It's hard to come across an artist or band that experiments with harmony, melody, rhythm, and timbre in meaningful ways, but Pink Floyd and Radiohead mess around with all of those very well, even if they aren't the top of the top for each category.
