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 CZcams in the development of neoinstruments" and mention this or something.

(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...

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
You have tried using steel, right? Mattias' quivering smile had me howling. Comedy gold!
First video I've REALLY ENJOYED for ages. Brilliant.
Nice to know that I am not alone in my woodworking skills. Have a few uke projects in mind (one started but on way back to drawing board cos I buggered it up). Now inspired to get going again. Keep up the good work. Subscribed.
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?
Jesus te ama muito!!! Tenha certeza disso
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.
You know he's getting serious when he pulls out the Mark Rober music
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!
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.

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.
I want to see this XD
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.
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.
thank you for making a dummy thicc guitar
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
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
I really enjoy your videos. There are so many great projects, and music-related which makes them especially interesting to me! Some of them have amazing results, while others, although they don't work as planned, are just fun to watch. I never know what I am going to see next!
It is so much fun watching you building this guitar😂😂😂😂
Good job!
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

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.
The balloon guitar is cool, but I knew from the beginning it wasn't going to alter the pitch at all (though maybe a small difference in the resonance from the balloon). I mean to say you shouldn't be disappointed it didn't change the pitch; you made a cool guitar that's exceedingly unusual, and that all by itself is cool.
He's anxious that the strings will break but I am anxious about how he puts those balloons. I feel like they'll pop anytime.
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!
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.
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
Forget the string breaking anxiety, i had balloon popping anxiety for most this video
I love that this actually worked, but very sad helium didn't make it super high pitched.
Double agreed😭
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.
You are a very interesting human and I am amazed of the way you think. You bring human ideas to the next level . I do the same to Multi-rotors and created my ideas to the next level and pushing the envelope until they fail but, I am retired now and trying to do some other ideas on whatever. Thanks for sharing ! Sub !
The resonant frequency of the string is not dependent on the medium in which it is played. Even if you had an air-tight chamber, filled it with various gases, and put a guitar and microphone inside, you would measure the same resonant frequency from the guitar string regardless of the gas that you filled the chamber with. You only get a change in frequency of your voice with helium because the resonant frequency of a column of gas depends on the speed of sound in the gas.

On that first attempt, it ended up making the tone brighter though. That's an interesting effect. Wondering if a heavier noble gas would give it a darker tone.
The different gases in the balloon won't change the pitch, but they might surely chenge the tone/timbre, in the same way that a guitar built with a denser tonewood like mahogany or rosewood sounds way different than a guitar built with a less dense tonewood, like Sitka/Pine.

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.
For anyone interested in why this doesn't work:
Strings are in air to begin with and its the change in speed of sound that changes the vibrations of the molecules.
The wavelength of the sound is what we pick up as difference in pitch.
When sound travels between different mediums the soundwave will shift by the ratio between what the speed of sound has in those medias.
What we have here is: Speed of sound in air (where the strings are) --> Speed of sound in helium (Where the baloon is) --> Speed of sound in air (on the way to your ear) -->Ear
The starting condition and the end condition is the same, so it will be the same.
When you speak with helium in your lungs your vocal cords will be covered in that medium when you speak. Then it will transform to a different wavelength when it shifts to the normal air outside.
Helium --> Air --> Ear
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.

The only way helium can change sound is if the strings are enclosed in a helium rich environment.
Even then, the difference will only be resistance to movement.
As to change in sound, it may just resonate longer as the mass of the string doesn't change.
That construction stuff is really cool. :) Thank you.
I just want to say congratulations for getting outside your comfort zone. I am proud of you. You gave me a new definition of air guitar. Thank you, my mind is officially blown.
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?
Liked and subscribed for your outstanding contribution to the art and science of fefe construction. Cleaving a balloon down the middle to emulate buttocks is revolutionary. Total game changer.
The reason the balloon works, I think, is because you're basically vibrating the whole balloon once you connect it to the vibrating strings (transfer of vibration). You send sound waves out into the air with the balloon instead of the wood.
That's actually a really cool build Mattias :)) I'm glad you're getting more sponsors and recognition so you can do more stuff like this

Thank you for this epic comment🤝 love you
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.
The fucking first balloon guitar you made was so cool. I really liked the sound of it

I'm a music person, this is the third video of yours I have watched and to be honest, you are very unique and oddly enough, I have had all the questions that you test in your vids. Thank you for answering them Mattias!
The pitch of a guitar (or any string instrument) is determined by the frequency of vibration of the strings. This frequency is influenced by factors such as the tension and length of the string, in addition to the resistance of the surrounding medium. To alter this property using helium, you would need to surround the string with helium. Since helium is less dense than air, the string will experience reduced resistance, causing it to vibrate faster and produce a higher pitch.
You could try placing (and playing) a guitar inside a vacuum chamber filled with helium; it should work.
Lol I get some Mark Rober vibes due to the combination of music choice and engineering :p keep it up!
Hey Mattias, I think it would be rad to put bass pickups on the low notes, then guitar pickups on the higher notes of a piano. You could then wire it all up and push it through a guitar amp, maybe even a cranked Marshall or through some cool guitar effects pedals or something. I don’t imagine it would be too hard if you could mount all the pickups on a board or something that could be inserted under the strings
Not really a good idea as that many pickups wired together would be a humming monster and would pickup all kinds of radio interference. You would have to have a mixing board with 88 inputs and a nightmare of cables the whole thing would be a miracle if you could get it up and running without any bugs. However if you used optical pickups then you wouldent have all those magnetic coil pickups hanging out creating a giant radio interference antenna and you could paralell their outputs with trim pots for ballance into a single cable thus eliminating the impedance nightmare!
Not being meen with the thumbs down .i like the idea but just not with magnetic pickups. It's hard enough to put 4 or 5 pickups in a guitar and ballance them without a hummmmm problem. Maby even use hall efect transistors for the pickups that might even be better than optical but would require more circuitry to put together.
that's actually pretty much the concept of an electric grand. there have been some made by yamaha, the CP series. but i'm not sure whether they used the same pickup or different ones across all the strings
@@michaelshultz2540 i think i have seen a piano with crystal pickups before, possibly even glued to the strings. Was a long time ago though.
@@ashtontechhelp thats an intriguing idea but in my experience with Piezo Electric pickups on guitars and violins its hard to get the deep resonance or body to the sound . But i think an optical or hall efect transistor would produce better more rounded tones. That combined with four contact mikes mounted to the sound board and given expression peddles would expand the preformance dynamic of the piano .and also adding magneto electric sustain/feedback would be another awsum extra.
Interesting. I think that as the strings are what produces the tone, changing the resonating body won't do much. Helium going through your vocal chords actually affects the speed at which they vibrate, but in this case it's like speaking regular air into a room of helium
Thank you for trying it out
Iy did sound slightly different, but I dont think changing the air within the guitar would effect the frequency that the strings vibrate at. So changing the pitch wouldnt happen as prominently as everyone would think. But I'm no engineer, I just play 1 in Space Engineers
Very professional with the briefcase guitar
Hahaha
Love it! But that piano with the fishing wire is still my favorite. Could you possibly do the same thing but with harp strings? I think they might be more resistant to detuning over time. I could be wrong.
Thank you! Yeah sounds like a good idea!
That was my favourite piano as well. I keep saying this, a nylon string piano needs to be a thing.
My little daughter picked up harpe playing a few weeks ago and now we have a professional harpe here. That thing goes out of tune while I'm still tuning 🤣
So, I don't know about the "more resistant to detuning" part.
I played classical guitar for almost a decade, so I have some experience with tuning cords. Harpe cords seem to be very sensitive to minute changes ...
I agree
Have you thought about maybe using something like the bladder from a camel pack backpack, filled with different viscosities of liquids to see how that sounds? Sound moves easier and farther through water, so....?
not you breaking the guitar string while you were talking about not wearing safety glasses and then it hitting you straight in the face 😭
Oh my, this video is going to BALLOON in exposure!
🎈😍😍
I think it’s because the guitar isn’t actually interacting with the helium gas, because the suitcase thingy has too thick plastic. You’d have to play it in a room full if helium for it to change the sound because the soundwaves would travel faster through the helium, but that would be pretty dangerous to be in. You could try putting a small balloon inside your guitar, popping it and then quickly strumming it, but I don’t think it’s entirely possible to experiment with this idea.
The ambient conditions (i.e. the type of air) will never affect the fundamental pitch produced by a vibrating string unless the drag force became significant. No configuration with helium will cause the guitar to play higher. The reason helium makes our voices higher is because air is the medium that's causing our vocal chords to make sound. On a guitar, it's the pick that does that. Helium doesn't just make everything higher; there's a very specific mechanism wherein helium has that effect.
That said, woodwind instruments could be much more interesting! After all, the gas vibrates the reed as it does for our vocal chords.
Edit: I just thought about it some more, and I'm pretty sure helium would not make woodwind instruments sound higher. I realized that the reed is resonated by the air to vibrate at its own, intrinsic natural frequencies. Again, the gas isn't part of that equation - it's just an arbitrary excitation, maybe it has something to do with the system being at its lowest energy state while vibrating whenever fluid flow of certain parameters is moving past it.
As for why vocal chords even get higher in helium, I can't even be certain anymore. Maybe vocal chords have mechanical properties such that the momentum of the gas molecules has a significant impact on pitch. Maybe this arises because they're really thin and more susceptible to gas? I'm just guessing now, let me know if anyone knows the answer.
@@Joe_Yacketori It will affect the woodwind instruments - the frequency is given by the resonance in cavity following the reed - after all the tone is normally altered by changing the length of the resonance cavity typically by opening or closing off holes.
@@MrXBT2000 Oh, cool! Thanks for the correction.
from italy ..i like kind of experiment and who take the best of his creative potenzial,so nice job!!
You have tried steel?? Right??🤣😅🤣
That line and look, cracked me up!!!
Wow it's really nice to see guitar prototypes that never really sold be put in to practice like this. You are great man
Thank you and it was a fun video to make!
Could you make an instrument out of a shed? Like use it as a resonator for a tea chest style bass, or add guitar type strings to it perhaps?
Wait, this is just a compact guitar... Genius design

Try playing Harmonica on Helium. Should be very simple and successful.
Hmmm yeah!😍
I got a pair of soundcore headphones from Walmart in 2019 and they still work like they just came out of the box in 2024.
The best headphones ive ever had, I thought they were gas station headphones because I had never seen them anywhere until watching this video right now 😁👌
I’ve never heard a ukulele be pronounced as “ukeh-Leh-leh”
I am happy Ive now heard it
Hey try sticking a mic IN the balloon! Since the helium is lighter than typical air, it'll vibrate faster. So the sympathetic vibrations within the actual balloon might be higher! The air around it will still vibrate at the same speed it always does. But the helium inside the actual balloon might sound different!
The boundary helium-air is the place where magic happens because of the sound velocity change, so for this effect to work it has to be: strings in helium, mike in air.
@@jupa7166 that makes sense... When you breathe in helium it's moving across your vocal chords. So it'd have to be surrounding the strings. Maybe a giant balloon the guitar inside would work😂😂😂
5:46 that chord reminds me of the beginning of “A hard Days Night”
The frequency of the vibration is controlled by the tension, length and the mass of the string. The resonance box is a way for mechanical energy of the string to dissipate more efficiently into the air as a pressure wave rather than the damping provided by the string end holders or fret. The bridge itself conducts the mechanical energy from the string end to the box. The box should have a large surface to move the air next to it. THe same principle applies to a piano. There is a soundboard in a piano. What gas is in the guitar box makes no difference to the frequency defined by the string.
17 seconds into the video and this gives me serious swedish vibes

Everytime I see you posted a new video (because the little bell of my subscription tells me so :D), I know my day is fixed :)
In terms of ideas, the only thing I can think of is making each hammer head on a piano be a tiny bow so it would strike the string as if it were a violin. I don't think it's possible, but if ever a person taught me ingenuity and perseverance can overcome any obstacle, it's you!
I do think your videos are very encouraging and wholesome, and I wish you the best in whatever endeavor you decide to tackle next :D
Greetings from Colombia!
Thank you so much! Yeah I’ve been thinking about this bow piano. There’s actually some attempts on it but that would be using rotating wheels etc. 😄
@@Mattiaskrantz I think Da Vinci himself invented a keyboard instrument with rotating bow like thingies. He called it viola organista if I remember right
Jesus is going to pass judgement soon. call on Him ! 😍😍😍
you could experiment with alot of different sounds with that contraption like attaché it to a sheet of copper or like have attachments for the guitar
