How an Organ Makes Music

[@KC-fb8ql]

just my opinion but I think this is one of the most fantastic contraptions ever created

[@darthlinathegreat7489]

What crazy is the fact that he’s not only just an organist, but he also had to tune it. This would be like a full time job, I hope that this guy gets paid good money for all of this labor he has to do.👍🤔🎶.

[@kanereynolds9521]

It's honestly amazing that people hundreds of years ago invented an instrument that complex and beautiful. Very impressive!

[@TheHomeWoodShop]

Thousands of years. According to another video, the first evidence of an organ being invented was in the 300s...............BC.

[@Trenz0]

The dude's wearing $150 hiking boots and playing a priceless organ. What a time to be alive

[@bremick]

I noticed that as well.. He could not play a complicated pedal piece wearing those..

[@teufelhunden8308]

What else is he supposed to wear? Stilettos?

[@oron61]

Kinda? They get narrow, soft-bottomed shoes of thin leather so you can feel the key through and slip between them, with the heels pumped about an inch and a half so you can play some notes with your heels. In older pieces you just used your toes since it took more force to push down the keys.

[@ejtamayo5317]

Totally agree

[@JewelBlueIbanez]

[@TorutheRedFox]

this thing is nearly like a bloody synthesizer before synthesizers existed

[@uhuhuhuhuhuh3537]

It is a synthesizer, just not an electric one.

[@bored.in.california2111]

I'm trying to wrap my head around the simplest parts of this and it's still difficult. I can't imagine how it was actually building it. Amazing.

[@Isegawa2001]

What really adds to the complexity of the organ is not the working mechanism, but the sheer amount of pipes and tuning that can be done. It is truly a glorious instrument, no wonder churches use it so much.

[@LucyAnyambula-tw5ri]

Exactly

[@Gallzatron]

But where does the air pressure come from?!?

[@organbuilder272]

Electric rotary blowers connected to reservoirs then, through pipes into the reservoirs in the chamber for final regulation of the wind pressure before entering the chests.

[@alexanderip1003]

[@kiragarvie]

@@AnonymousUser-lf6mc They had bellows boys! People who stood back there and pumped the air - some organs today have the option of being hand-pumped.

Heaven. From the heaven. Lol!

[@aortaplatinum]

Organs are so INSANELY cool, these giant, imposing, massively loud and somewhat terrifying instruments that you have to climb up inside of to maintain, capable of flooding an entire building with sound from just a relatively small pressurized air well. Being able to even emulate the sounds of other instruments, it's like the ancient god megafauna precursor to MIDI or a keyboard.

[@kansasthunderman1]

In addition to the sound of the organ, the church also has very good acoustics.

[@dinosaurcomplaints2359]

A lot of the old churches were designed with acoustics in mind. Some of the organs were built specifically for the space of the church. Bach’s toccatta and fugue in D minor is one of my favorite pieces. If I could only play it!

[@teebz5739]

The organ - such an underrated instrument, these days. 🎵🎵🎵 It's basically an orchestra in a box

[@Alex_Mewtwo]

thats its purpose- to be capable of replacing an orchestra however, i would say it isnt just “in a box.” i think saying that is disrespectful to an instrument that is the size of a building

[@kmno4216]

[@kazunne4530]

[@amietedeschi3203]

Altogether, John is in charge of 12 organs, four in the Chapel alone. He also tunes the university's harpsichords.

[@joshygoldiem_j2799]

I was just about to say that😆 That guy must be very, very patient

[@stephenharper11]

He is musically educated, but much of his work is routine tuning -- very, very precise work. The general maintenance and repair work is really a combination of mechanical engineering, physics, and craftsmanship with different woods and metals.

[@raymondraptorclaw2901]

So the pipe organ was basically the original “electric piano” in the sense that it has the ability to play different instrument sounds?? That’s amazing!

[@Turnpost2552]

comparing it to anything today is seriously underestimating the influence this instrument had over centuries

[@iLumberjack]

It is more analogous to an orchestra, although the larger ones can produce a sound more powerful than any orchestra. The pipe organ was for centuries the most technologically complex machine humans were capable of producing.

[@DonPedro6901]

Amazing how you are able to tune so many thousands of pipes.

[@harrybeau1712]

Not only mind-boggling in its complexity BUT the present players and repairers of these fantastic instruments must find people to whom they can pass on their knowledge or else...

[@andreson21]

Finally I got courageus in getting to know how a organ works. Thanks.

[@calvinryden2589]

Great video.

[@fburton8]

Great presentation! What I find quite surprising is how the organist doesn't need to exert a huge force through his fingers given all the times the action needs to be transferred between the different rigid parts. I'd have thought the cumulative friction would make the key hard to press.

[@fburton8]

P.S. My grandfather used to tune and repair organs as well as pianos, including the organ at Hereford Cathedral in England.

[@kansasthunderman1]

The tracker action is a major component of this type of organ and minimizing friction is an art in itself.

[@ebutuoyrwd]

You get enough things coupled together and it does get harder and harder.

[@oron61]

The tracker opens more and more pallets/doors-for-each-pipe with pressure against them the more stops you pull out. You can make it so you have to put your full weight on a pedal key if you were crazy enough. With electrics, it all feels the same no matter how loud you get.. Between those, they started using the air from the pumps to make the keys easier to press.

[@brandonschoen5047]

[@jdjones7855]

I was more wondering where the air pressure came from both in modern time and the old days but still very cool video

[@nicktheharpblower]

Hi Jd Jones, that’s a very good question! Us organ builders call the pressurised air (as you describe it) ‘wind’ and It’s measured in cubic feet a minute for flow volume, and inches of displaced water for wind pressure. Inches is traditional, but we also use mm now, I think this started in the 80’s? We tend to use a electronic wind pressure gauge as it’s more accurate. Pressure most commonly ranges from 2 ½ to 10”. The voicer sets the final pressure in the building, and it’s done in different ways depending on the reservoir used (we call them rez’s in the factory by the way). Double rise reservoirs have to be weighted, and single rise reservoirs have to have springs. The pressure in double rise reservoirs is consistent, and it doesn’t matter if the rez is full or nearly bottoming out. This is due to phase cancelation. The top frame, mid frame and well is connected together with a ‘counterbalance’ to ensure all the pieces move as one. Alexander Cumming, who was a clock maker, invented the horizontal double rise reservoir around 1787. Single rise rez’s give a higher pressure when they are nearly closed, so springs are used as they decrease steadily. Another type is called wedge bellows, these are used in ancient organs as well as neo baroque organs, there is also a regulator called a schwimmer. The history of organ blowing is exhaustively long to be honest, first the blowing was achieved by hand/and or foot dating back to the ancient Greeks, then steam power, hydraulic engines, crank gear that was driven by electric, gas oil and hot air engines and then finally the centrifugal fan which we call the blower now. Hand/foot or machinery operated organs have ‘feeders’ which inflate the storage rez, these are basically mini bellows that can be wedge or single rise in shape. Some famous British organ blowers include BOB organ blower, Watkins and Watson and laukhuff. Henry Willis once said “The most difficult thing in an organ is to move the blowing lever up and down”. Hope this helps!

[@teebz5739]

I think people were smarter before. We’ve been dumbed down, not by accident. These instruments and the bells (not so much now) and the acoustics they create in these specially designed spaces for the sounds are so healing for the body with the frequencies they emit

[@James_Bowie]

At 3:15 .. in fact the opposite. 'Shall-OT' is the vegetable. 'Shall-et' is the reed pipe component.

[@andremartines5061]

I've never seen a video showing what moves all this. From the oldest to the newest. Where does so much air come from?

[@KingGrio]

Very instructive, thank you

[@TayTayChan]

Great stuff

[@chrisrosenkreuz23]

I still don't understand what blows the air... Aren't there bellows or something? He just said pressurised air goes into the pipes but how does that happen? What pressurises the air, what makes it blow?

[@justinnaramor6050]

I apologize if this reply gets long, but here it goes: as far as I'm aware, pipe organs have what's called a "windchest". This acts as a reservoir of air. If you understand how bagpipes work, for example, this is similar to that. So I presume the windchest is what "pressurizes" the air... it inflates like a balloon (or... like the bag in bagpipes!). And as you're probably aware, any time you squeeze air into a smaller space, such as a balloon, it becomes pressurized; this is now 'compressed' air. So, my thinking is that the bellows (or electric blower, in more recent times) simply supplies air to the windchest, which then supplies that air to the pipes. The windchest has valves on it, one for each key. So when you press a key, a valve opens. So that air in the windchest then escapes into the pipe to make sound. Release the key, and the valve closes, cutting off the sound. The object, then, is to constantly keep that windchest inflated with air in order for the music to keep going; stop pumping air, and the music cannot progress forward even when the keys are actively being pressed... because at that point there's nothing to provide a constant airflow. This is my observation based on my (very recent) research into how pipe organs work. You're right, this video really didn't do a good job at explaining the air-supply portion. Seems to be a problem with videos like this... it's like they assume you know how air is being supplied to the pipes... which is nonsense. There are people who have absolutely zero understanding of how pipe organs work, particularly with the air supply part... so people should really try and explain that more thoroughly and correctly so other people can truly understand it. But I do hope my explanation helped you understand it a bit.

[@darthlinathegreat7489]

The ceiling might collapse on you, that almost happened at my church because our organist tends to do that a lot. Sometimes while he’s playing it I would often check the ceiling (Plz do not fall)! Thank god I don’t go to that church anymore it’s a very small chapel though, it’s hell of a lot louder than you think in small space like that👍🤔.

[@stephenharper11]

Recently I have been checking the decibel level. Each of the great organs sound loud in the building at 70-75 db. However, I feel that either one could create more sound depending on registration. I will update this reply.

[@WildtuinMichael]

Thank you for this informative video. One thing I don't understand is the tuning part. What are you doing when you're tapping that pipe with that stick? How does that tune it?

[@tavoh3200]

I imagine it's a magnet

[@kansasthunderman1]

He's adjusting the tuning wire that controls the tension and frequency of the reed.

[@shiningarmor2838]

That tuning wire he pulls off changes the length of the reed, and the length determines the frequency.

[@onemoremisfit]

With the reed pipe that was shown, he taps that wire clamp that wedges the reed in place, and as the clamp moves, the reed's vibrating length changes. The assembly is wedged in place by friction, and light taps with a tool change its pitch by moving it slightly. On flue style pipes (not reed) there is a short telescoping section at the end of the pipe that is also wedged in place by friction and tapping the end section with a tool will effectively lengthen or shorten the assembly in order to change pitch.

[@davidjames1684]

Do you tune the pipes to each other or to an actual pitch such as A=440 Hz?

[@DanielSarkela]

David James I’m sure that A is tuned to 440hz and he was just tuning the pipe using another C# as a simple demonstration for the video

[@kiragarvie]

That depends on the organ. Many organs will be at 440, but some historic organs are tuned to different pitch levels and different temperaments - not all are equal-tempered.

[@stephenharper11]

The four organs, harpsichord, and piano in Duke University Chapel are tuned so they CAN be used together. But there are minor things differences due to heat and humidity. "Together" does not necessarily mean "simultaneously". For example, a processional hymn may start on the Flenthrop for verse 1 and 2 then verse 3 and 4 may be led by the Æolian as the choir reaches the Chancel at the front of the long aisle. There are some compositions that call for two great organs. For example, a Mass by LouisVierne which we have performed.

[@jelenakonstantinovic114]

Woww👏🏼👏🏼

[@sashineb.2114]

How does the device in his hand tune the pipes? What is happening inside the pipe when he is drawing the "wand" over the pipe? Thanks.

[@DoomFinger511]

That tuning rod he showed that was next to the reed is what tunes it. If it's longer or shorter it changes the pitch. When he taps the pipe it wiggles the tuning rod and makes it move down slightly until it's the right pitch. He will manually pull it higher with his hand, then tap it with that stick to slowly wiggle it back down until it's at the right distance.

[@martintrueloveistherealmag3937]

I think churches were healing places and the ones who had an organ playing were working thru sound frequency..... thats why they are called organs... different frequency for different body organs.

[@shaneconner174]

Where did compressed air come from back in the day? A steam engine? Was there a crew shoveling coals into a furnace to keep the organ running?

[@DavidDaringer]

According to Wikipedia they used bellows.

[@AndresMorales-wc4pg]

The air is produced by an electric fan, the air produced is stored in a large bellow that works similar like a lung, it keeps the right pressure, and then all the air is distributed through the ducts.

[@samschaeffer8236]

In earlier times, when they could not have electricity to run blowers, the wind pressure could be raised in several ways. One way was human power. One or more men could work levers by hand or by foot to pump air into the reservoirs or bellows. Another method was to use weights and pullies to allow gravity to pull the weight down, thereby converting downward motion into rotary motion to turn the blower. Of course you would need a tall enough bell tower or other structure so that the weight could work long enough, before having to reset it. I have even read accounts of gasoline engines being used to generate the power needed in some cases. This may have presented problems with fumes if the engine were not placed far enough away from the building.

[@tedphillips2501]

And then there is the marvelous Aeolian organ. Note: never touch or blow a reed pipe. Always use a dollar bill - It is linen and will keep body oils from harming the reed.

[@zshathickhaque]

[@heavyglassglass]

Still don't know how it makes music

[@CustomTies]

same as a tin whistle, but rather than having holes there are wider pipes.

[@oron61]

The stream of air coming out the pipe sucks a little vacuum from the pipe body, which makes the outside air push back in to get rid of this vacuum, bending the stream of air. This goes back and forth, turning the stream of air into an invisible reed that vibrates. Basically it's done through sorcery.
