sounds really trippy!
Spooky sound 😮 great engineering
Thank you 🙏
Great video! Love the haunting sounds of the wind harp.
Ohhh I love these things. Nice work!
💕💕💕 Thank you for sharing.
Nice job ... thx 🎼
Thank you for your very detailed explanation. I shall make one. But broader versus taller. Shall look for designs.
Let me know how it turns out. I would love to see a video of it
@@RajGiandeep shall video it.
These are what people are hearing as local hum
Cool )))
Really cool! I think that's a fisherman's knot. I want to hear the wind play it.
Here is a different video of the same harp. Just playing in the wind.

So Raj, I’ve had an idea for these for a very long time. I’ve wanted to turn one of these into an actual electrical generator by forcing this to tension with piezoelectric elements. Or so that the vibration of the string creates a vibrating tension in a piezoelectric element and therefore produces an alternating electric potential to the same frequency as the note of each tensioned string. I know it would be micro volts generally but I just imagine like a 8ft by 4ft quart with 100s of strings tensioned down the 4ft length. Sticking that up In the wind all the strings would vibrate and create alternating currents in the piezos element. With a bridge rectifier that high frequency AC could be turned into high voltage pulsed DC. And can be used to charge a battery..... what are your thoughts on this?
It would essentially be an array of strings each with a piezoelectric power generating element just like this system. czcams.com/video/ZWaCnODSBfM/video.html
One of the big reasons I like this is because piezoelectric elements have much much higher efficiency in power generation when the alternating mechanical force on it is near the piezo elements resonant frequency. Which generally is pretty high. A lot of people try to do this with like putting one in their shoe or on the ground and they are doing very small rate of alternating for the stresses on piezo element and they just don’t yield a lot of power. But with the strings vibrating at audible frequencies it would be very easy to find piezo elements that have resonant frequencies in the audible range.
I came up with this idea years ago when they installed a wind harp in the middle of campus where I went to university. They put it at a part of campus that was known as having like a wind tunnel effect and it made the wind har work a lot.

@@CharlieSolis This would be an interesting project. I've never seen a metal wind harp up close. Curious how they tension strings & how the vibrations transfer to sound without a hollow tube.
@@RajGiandeep that’s a good point. it’s funny you say that because it’s kinda disappointing with how quiet it is. It doesn’t have a good amplifying body. Like you do with your tube. And as I’m sure you already know like how the wooden body of an acoustic guitar helps amplify the vibration into sound.
What I just realized though is that the more vibration that is lost to sound the less what will be harnessed in energy. So as a wind harp with a tube it makes better sound. However if it’s made to not vibrate an amplifying body we can get it to drastically increase the power production at the piezo tension element. Thanks for pointing that out too because this has me thinking about how to amplify the efficiency 🤔🤔🤔
Hi I love this. I manged to get my classical guitar working yesterday. The G B and E all tuned to G-B below middle C. I was so happy lol. With your harp do u find it works better with the bridges being so High?
With the plastic pipe, it's not straight. More so with a long 10 foot pipe. So I needed the higher bridge so it wouldn't touch the pipe. I don't think height matters, just tension & free from touching harp body itself.
Glad you got your guitar working again.
@@RajGiandeep Have you made any more like different builds? I just love aeolian harps man. Im going to start messing about again now that i can get the string to sing finally! Taking a classical guitar outside is a great place to start for anyone new. I was suprised it worked.
Have you tried really heavy nylon string? I think there is 100lb line. The crazy thing is not many people have heard of an aeolian harp yet they used to be common in europe near 200 years ago. Every home needs an aeolian harp now though. I know most don't have sash windows anymore but there must be a way to design one for push out windows. The sound is so flippin amazing. Have you experimented with dif string thickness and dif lengths? For example do longer ones need thicker string? Nice talking to you.
@@phoenixrising1576 I have made a metal one, it's on my channel too. Different sounds from the plastic. I prefer the metal one as far as sound goes.
Guitars sing in the wind too? very cool
Heaviest nylon I tried for this build was 30lbs I think. I would want to use metal with the 100lb line to hold the tension. I'd think it would work. I did actually buy some metal pipe. I think 3 inches. But don't have the tools to drill it properly & not sure how to mount it. Very heavy.
I would like to attempt a window version at some point.
On this build I use 5 different weight of string, varying in size from mmm I think 10 lbs to 30lbs. Could probably go a bit higher.
I'm curious to have a way to funnel the air into the harp when outside better. So it works in lower wind speeds.
@@phoenixrising1576 Made a window wind harp -> czcams.com/video/s_bmmN6Del0/video.html
I made one following your video; I cannot hear it. Any tips??
If you pull the string and you hear a sound. Your probably good there, don't need the strings really tight, just enough to make a good deep sound out of it. You need a constant steady wind that's at least 7 - 11 miles an hour to get it to sing. Once it's steady it will start in a few seconds. If you live close to a canyon. Take it there at night.
Let me know of any other questions you have.
Thanks for replying. Our local weather says our winds are 14 MPH and it still does not make a sound. I am in NYC and it is very noisy maybe that's the problem. But I agree with you it should make a sound. I have made 6 of them and placed them in different sections of my yard. Will keep trying. Thanks again
@@deerivera9033 can you share a photo or video of the top & bottom of your wind harps? How tall did you make them?
It's 56 inches tall made from copper gutter pipe. I attached a photo not sure if you can see it
@@deerivera9033 don't see the photo. when it's a gutter pipe. I followed the advice of this video below. I'm curious how you attached the strings. did you fill the cavity at the top with wood to have something to screw into? do you have bridges? try to upload a photo here imgbb.com/

If you made holes in the black pipe would it be louder? Like the hole in a guitar?
I've wondered about that. I wonder where & how big of a opening
@@RajGiandeep I think that depends on how much the pipe is resonating. Plastic pipe is a great choice for rigidity and weatherproofing but maybe not so good for a sounding box. Perhaps fitting a 180 degree bend to the top would direct any sound downward?
I was wondering how loud it is? If you don't have a means of directly measuring the volume perhaps you could tell us from how far away you can hear it over the sound of the wind? Nice design btw.
@@skelly790 I've made 3 wind harp, wood, metal & plastic. In general they aren't very loud by their nature. As far as how far away you can be from the wind harp & still hear it outside clearly. I'd guess 25 - 35 feet or so.
The body of an instrument is like an amplifier. All the hole in a guitar does is let the sound leave the instrument. The strings don't actually make the sound on a guitar. When you pluck the string it sends the vibration into the wood of the guitar via the bridge, and the vibration travels through the wood into the body and bounces back out the front sound hole.
If the hole in the tube is at the end that's where the sound exits. More holes /larger hole the less depth the sound will have.
There's a different kind of windharp with no body at all but instead used a cone to amplify the sound.
@@brandengillette7794 since I can remove the top cap. I'm curious to remove it & see if it sounds much different or to attach a curved pipe at the top to direct sound down.
