The string breaking anxiety is so real bro.....I was sweating
When string break at that point i probably left the string there with the instrument

Just put some graphite on a saddles under each string to reduce friction. You can "draw" it with ordinary pencil.

Hi! I'm a physicist-turned-engineer who has studied the physical acoustics of guitars somewhat extensively (it was the subject of my undergraduate thesis). Unfortunately, I don't think anything particularly interesting can result from using helium with a guitar. The PITCH of the guitar is strictly a property of the stiffness, length, density, and tension of the strings themselves--they won't turn into ukelele pitch unless you change one of those things. This will be true with any stringed instrument. But, the pitch is not the only property of a guitar that can be altered. The thing that miiiight be possible with helium is messing with the impedance of the body of the guitar, thereby altering the coupling of the strings with the air. This is what's happening with the balloon piano, I think (though I'd need a better look to be certain): the soundboard of the piano is FULLY enclosed in helium, or at least enough to be a significant impact, and because helium is much lower density than air, it couples poorly with the air, causing the sound energy to be retained inside the balloon--resulting in the quiet, long-sustaining sound we heard. There may have also been some resonance of the balloon itself happening there, but that's only going to be a filtering effect on the sound of the strings, rather than pitch-shifting them. That said, a guitar doesn't really use the air inside its body for coupling with the air--most frequencies travel directly from string to bridge to wood to (exterior) air. The bass frequencies ARE affected by the interior, as the whole body flexes together when the wavelength is long enough. The hole is present to allow pressure equalization. This does provide some (helmholtz) resonance but I expect that a change in this resonance will not dramatically affect the guitar's sound. What might be cool is if you (somehow) put a balloon around the ENTIRE guitar. I think, because of increased mismatch of impedance, you'd have an increased sustain on your notes and an overall quieter tone. Depending on the shape of the balloon you may also see some high-pitched resonance filtering on your tone. But the pitch, coming from the strings, will be largely unaffected.
guitarist and physics student, i agree. basically, it will make the sound brighter and emphasize higher pitches alightly more
Mans wrote the whole bible
This experiment is an example of wasting time. Free of logic.
Physics student and guitarist, I also agree because if you think about it, it’s string that’s making the sound and not the sound hole, all the body does is amplify the sound, what would shift the pitch of the guitar is a different string material, which we already do but we don’t notice it as much because we tune it to the right note anyways.
History student and i know like 3 songs in guitar, Ive absolutly no idea what half of you guys are saying mean but I agree with you and i dont have anything else to add... But if you group and make a thesis on helium based instruments i could do a "History of the use of educative TH-cam in the development of neoinstruments" and mention this or something.

Helium does have a big effect on how the balloon resonates.
6:17 Without Helium
6:53 With Helium
I mean right?! The overtones are completely different, it almost sounds like a 12-string when filled with helium.
Don’t click the link/press more
Together, let's report that spam
Exactly! No helium sounds richer, I believe.
Speed of sound in the balloon changed from the change of medium changing the properties of how the sound act with in but it does not change the pitch because the pitch we hear is based on the frequency of the balloon surface interacting with the air. The whole room has to be in helium for it to affect the pitch
(The Helium has to be around the strings, this results in less “air” friction, and the strings can swing faster.)* So if you play a guitar in a room filled with helium it should have a higher pitch, than in a room with air. They did this experiment in a German TV Show, but the video is currently not available on the web.
*edit: this is physically not correct, I was wrong!
I believe this is true. If he'd put a small toy piano or something into a helium filled box I'm pretty sure it would be higher pitch. By regulating the mix of air and helium one could even do like a vibrato...
He's going to die for that to happen
@@turboanalyst2628 worth it

You can't hear anything in helium lmao
thank you for making a dummy thicc guitar
You have tried using steel, right? Mattias' quivering smile had me howling. Comedy gold!
Essentially, if you couple your guitar to a helium balloon instead of air, the actual pitch will be no higher (the same as with singing) - you shifted only the resonance frequencies, i. e. the formants of your resonator. This makes it sounding "smaller" and somehow higher, though the pitch essentially is the same.
Good explanation!
Yes you can modify the resonator's formants in a physical modeling synth in real time to really hear what's going on, sounds pretty neat!
Which is exactly what you can hear at the very start already. Instead of a mellow tone, it sounds sharper
I believe it also gave it less sustain. What I wonder is if sulfer hexaflouride would give it a fuller sound with more sustain.
Put another way, it's like turning up the treble knob.
This would actually work if you fed a set of bagpipes or an organ with a supply of helium, or played a clarinet or a flute filled with helium with your lungs also full of helium. It doesn't work with a guitar because the characteristics of the strings themselves determine the frequency, whereas with woodwinds and reed instruments, the characteristics of the the air column inside the instruments determine the frequency.
Let's not try going for the lungs full of helium please. ^^;;;;
That is a nail on the head explanation of the true physics of how and why helium changes the pitch in your voice and other reed and wind insturments. But if you could hear in a vacume the pitch of any string insturment would not show a significant change in pitch . Now to the other extreme if you played string instruments under water or oil or mercury then you could drastically change its sound and pitch. Maby put the bottom of the strings on the upright piano in a fluid tank and mike the tank.
👍
Watch Trent Hamilton play the Tuba or Trumpet with helium
sounds like one way to die
You know he's getting serious when he pulls out the Mark Rober music
It is so much fun watching you building this guitar😂😂😂😂
Good job!
I wonder if the baloon body could be used on other string musical instruments, like violin and how it would sound - I mean, it works on guitar, so it could work on other instruments too :/>
Yeah pretty sure I read it works great for smaller instruments but double bass and all that stuff didn’t sound good because of the large body. That’s all I remember
I mean, I remember my electric guitar touching my cabinet and the sound being amplified. So really, anything can be an amplifier
TwoSetViolin flashback to violin-chan and Davie504 war.
@@improvingguitarist1595 what you just described is literally what an acoustic guitar does, it’s actually really cool how it does that. Generally a resonator just has to be flexible enough to actually amplify the vibrations, be filled with a fluid (whether liquid or gaseous), and have some way to get the sound from the resonator into the air. I may be wrong on a few things, though, as I’m just using my knowledge of physics and a bit of intuition and experience.
More tricky in a violin I think, as it has bracing posts underneath the bridge, which would get in the way of a balloon
Physics major here: Because the helium is the amplifying medium and not the producing medium, there is not as much of a shift in pitch. The actual guitar strings themselves would need to be encased in helium in order for the pitch to change.
Would encasing the strings in helium increase the wave propagation speed in the strings or somethin?
I think maybe a low mass density material were to be used for strings that could potentially increase the pitch under same string tension...
@@manansvoicenstrings2962 - yes! you can see that mass density effect with 'wound' vs 'plain' strings on guitars etc - and nylon or gut strings vs steel and other materials.
it wouldn't be pitch change tho would it? I would think it'd be more like formant shift
In other words if i inhale helium and play flute or saxophone it would change its sound right?

So I did some research, and apparently it's the distinctive drum-like body, rather than the strings, that give the banjo it's distinctive sound.
So you could make a piano with a giant drum for a soundboard, and in theory it'd sound something like a banjo. A pianjo, if you will.
Yeah, this is probably one of my dumbest ideas yet.
this is precisely the kind of idea that should be posted in the video suggestion part of his discord
Yes! As a banjo player, I approve this idea.

Ooh hey Casey! This is weird. You know I actually bought a banjo while making this video because I was convinced it’s something I could do with changing that drum like you said. But I’m not sure exactly what the title would be. Like I put a kickdrum on my banjo? Idk lol
@@Mattiaskrantz That title sounds good, to be honest. Maybe do the same for a guitar, so you can name it "I put a kickdrum on my guitar and my banjo". You could even use editing magic to make a small song using both instruments, if they sound decent. I don't mean editing the sounds to improve them, but to overlap them properly for the song.

I was impressed by the build quality of the balloon guitar, despite you having said that you don't really have good skills for that sort of thing. The end result sounded pretty nice, especially with the blow up suitcase!
Here's an idea: a piano that always plays the song you want, regardless of what keys your press.
My thinking was that you could have a raspberry pi to do the logic, have all the keys trigger something that checks what the next note in the song is and then plays that note by either hitting one of several preconfigured strings OR hitting a single string that gets adjusted to the right tune dynamically (by servos, motors, or something).
The lego grand piano kinda does this, although it's done electronically. Many electronic midi keyboards targeted towards people who are learning to play also do this.
Haha that is nice. You could impress girls with that :D
Self playing piano?😆

This is what science is all about! Kudos to you for doing the experiment even though it wasn't guaranteed to work out.

As an electronic music producer:
You haven't changed the pitch, however you affected the tone of the guitar.
What putting a helium vs normal air baloon does is similar to using an effect like an eq/filter/saturation. You essentially just change the harmonic content of the sound, not the pitch itself :P
Yeah it sounds so much brighter every time he uses helium, it's kind of amazing. Even the very first run where he just haphazardly sprayed some helium in a guitar body it was appreciably brighter.
I 2nd that the tone changed i have 30 % hearing in one ear and still could tell the tone changed.
Good to know
Still really interesting though! By varying the gas in the chamber and the material of the strings you could probably get a huge variety of tones and “feels” out of the guitar by getting different ranges of harmonics, almost like an acoustic additive synth.
I noticed that too, and I'm glad you shared this info, thx

It's impressive how good a balloon guitar sounds. I think it uses the same principles as an acoustic guitar. The soundwaves reverberate inside the balloon the same way it would in an acoustic guitar. But the flexibility probably allows for some neet effects.

I have an idea for a piano build that I always thought would be interesting: A bowed piano. Essentially whenever you press a key, it wouldn't use a hammer to strike the string but a bow to vibrate the string, similar to a violin or cello. I think the way it could work is you build something to a giant belt sander perpendicular to the plane the strings are on, and then pressing a key for a note would, instead of hitting a hammer to strike the string, would push the string up into the belt sander. And obviously instead of sandpaper it would be like bow material that is waxed up with rosin. You could get the sound of an entire string orchestra through a piano!
Look into the "Viola Organista" it is an instrument designed by Leonardo da Vinci using that concept!
That is called the hurdy-gurdy.
Like John said, it exists and is called a hurdy-gurdy!
Some people mentioned hurdy gurdy but I think your idea sounds much more similar to the Nyckelharpa, a Swedish folk instrument made famous in Dalarna
They already do this. All you do is thread some horsehair around the piano strings, and sway them back and forth to create the tone.

I love that this actually worked, but very sad helium didn't make it super high pitched.
Double agreed😭
The pitch is determined by the vibrational frequency of the strings - this *is* presumably affected by which gas they are vibrating in, so you'd have to put the strings themselves inside helium, which sounds pretty difficult :P
Yep! Couldve spared him some hours.. But that's accurate
Yes, same thing with your voice actually. Did a brief experiment with a vocalist friend. It emphasizes the higher overtones, not raises the pitch. Otherwise, the new sound would just be a female voice (if male). The new sound is entirely unique.
But then maybe he could put helium inside a piano? Like, seal it and make a valve to put the gas in maybe?
@@003Pookie do you mean that breathing helium doesn’t change the fundamental note, but only increases the volume of the overtones? If so that’s really interesting!
@@grainsintherain Great idea!
Just subscribed!! 😁
Cool video!
what i love from his videos is the fact that he solved all of his “ impossible ” & “ nonsense ” problems .
Jesus te ama muito!!! Tenha certeza disso
The thing is that when waves change medium their frequency doesn't change. However the frequency of your vocal chords in helium changes which is a totally different effect.
Nope, doesn't affect vocal pitch either. Just the formants. Might possibly make singing some high pitches feel easier due to the way vowels work.
What about inhaling helium and playing through a woodwind instrument?
So if it string where surrounded in helium that would raise its pitch
_Strings_ are unaffected by medium in their pitch. However, any wind instrument (and voice is physically speaking a wind instrument, yes "vocal chords" are not real strings) is.
@@DCBfanboy pitch is determined by mass length and tension of the vocal folds, very much like a string.
Thank you for trying it out
luv the mark robber music
The reason this doesn't work is because the pitch comes from the vibration of the strings. Having a lighter gas on the interior wouldn't change that. However if you had lighter strings you would, hence lighter gauge strings have higher resonant frequencies. Interestingly the helium guitar idea could work in theory if you had helium strings instead. Imagine a straw-like string that you could fill with gases to create different variables in the pitch. That in theory would work - but I'm also not sure how you'd actually thread something like that.
Hey Mattias what if you made a piano that has piano strings and guitar strings so you can switch instruments. (Like on an electric piano)
Hahahh yeah that one is good
A good piano has three strings per treble note, so maybe you could have one piano string, one guitar string, and one other instrument string, and then separate dampeners for each type of string...
@@SqueezeboxOfDelights yeah i was thinking something like that. And maybe have a far right and far left pedal to shift the mallets over so they play the other strings
@@Mattiaskrantz i might say: half the piano is guitar strings and half is piano strings so you can like play a main melody with guitar strings and play piano chords with your left hand?
the guitar timber or any other instruments doesn't come only from the string used, guitar strings on a piano would sound just like a weird softened piano, because there s still a small hammer hitting the string, and not your fingers pinching it, which produces a much different sound.
Looks comfortable 😁

I had a similar thought about that a couple weeks ago. All the string instruments play in various ranges, so a piano with the strings of an instrument within that particular range would be pretty cool.
this is a funny idea
That was freaking COOL
one thing u may have missed is the sound quality with the large blue balloon and the bloon suitcase were FAR better then the acoustic panel of the wooden box diaphram. you discovered a HUGE leap in sound quality for guitars, make a 111 percent pressurized perfectly sealed pvc diaphram and nestle it like u did with the baloon. youll make at leasta couple million.
Well I think your guitar with the handle is just lovely. And you can always tune all the strings to HEHEHE (German note names!), inhale a bunch of Helium and then just have fun anyway!!! And mad respect for posting the results despite it not going to plan. That puts you in like the top 10% of all researchers, since many just keep very quiet if their hunch doesn't play out...

6:54 me every time luthiers show off their concrete/plastic/pencil/cardboard/glass/skateboard/ribcage/etc guitar body and talk about it's "TOTALLY UNIQUE" sound as if it has any effect on the parts that actually produce sound
I've broke so many guitar strings before. Here's my tip: New strings are brittle, older strings are more malleable. So the trick is you tighten it just a little bit (maybe instead of E you tune it to a B), the string would stretch itself out and get out of tune in a few minutes. Then you tighten it again. The string needs to ease in to the tension.
Weird, I've always just tuned new strings a whole step sharp then slacked them off a minute or two later. I can't remember the last time I broke a string.
I stretch my new strings manually by pulling on them in the same motion that one would cast a fishing rod.

Put an electric guitar into a vacuum chamber. In theory it should be possible to adjust pitch by changing the air pressure (thus changing the density) inside. Or put an accoustic guirar into a helium chamber. Your voice becomes high pitched in helium because your vocal chords vibrate faster in a gas of lower density.
But how would he play the guitar if it’s in a vacuum chamber?
Ok but that balloon got me acting strange 😩
Also here’s an idea: can you make a guitar that has piano keys that cause hammers to come down and smack the strings?
That’s a great idea😍

And then it had a guitar where you could press keys which would act as a hammer on the strings.
Someone's actually built one. Can't find it now but if you can imagine six piano keys built into the side of the guitar, with six hammers inside that strike the strings through a hole below the sound hole.

The fucking first balloon guitar you made was so cool. I really liked the sound of it
Thr shape of that balloon is my favourite
The frequency (pitch) is determined by the strings moving up and down. In order for the strings to change frequency to a higher pitch they would need to move faster either by increasing tension or reducing the atmosphere resistance(drag). Volume of the sound would affect how much vibration is transmitted from the strings to the air, this is where the body (balloon or wood etc.) would make a big difference. The body and resonance also determines where/how the sound is reflected and how the decay of the sound is shaped.
Try playing Harmonica on Helium. Should be very simple and successful.
Hmmm yeah!😍

I think The only way to get the actual fundamental pitch higher would be to fill the entire room with helium, otherwise it’s only the overtones that go up in pitch because the string is still vibrating against regular air
