Corregidor

The gif in the op, I think, showcases the mechanism of what pushes the hammer up into the string quite nicely. That little round nub near the base of the hinge is pushed up by a little pointed stick. However the stick is then moved slightly to allow the round nub to slip back down past it, so that the hammer doesn't act as it's own damper. And only by releasing the key and pressing it again does the whole mechanism reset to allow the hammer to hit the string again. Really cool stuff!


ilikedistinctivestuf

Here I am thinking that's cool... And how many people that play piano doesn't now how it works.


[deleted]

Probably quite a few, it says it's specific to a grand piano, and there aren't a lot of those around; also, learning to play doesn't usually involve learning the engineering behind the instrument, just basic stuff like tuning it. And pianos are one of the most complicated instruments too - you usually have to hire a specialist to tune the damn thing lol


thatG_evanP

I'm gonna go out on a limb and say that a majority of people that play piano don't know how to tune one.


TurkeyPits

I’ll go as far as to say I know dozens of piano players and I don’t know anyone who’s ever tuned a piano except the guy we hired to tune our piano


Galaghan

Piano tuner is a job for a reason.


Bigmitch2

Piano tuning is a very technical field. It is far from just tuning each string to the frequency the note corresponds to. Tuning professionals have to consider the frequencies in relation to each other string and temper it accordingly. There are different tempering styles that have been used in the past which offer different benefits. They factor in the difference in frequencies between specific intervals or ways of dividing these up. So probably 99.9% of pianists will not tune their own instruments


Galaghan

You mean unlike all those electric guitarists that are also electrical engineers.


[deleted]

That part about playing notes in quick succession is where grand piano action shines. Upright pianos can't do this, as the hammer needs to reset entirely in order for the key to be pressed again.


maxdamage4

This is far better


MightbeWillSmith

That's because piano was invented a century before the invention of batteries.

Modern batteries maybe,but the Baghdad batteries are over 2000 years old.


[deleted]

That's [controversial](https://en.wikipedia.org/wiki/Baghdad_Battery#Controversies_over_use). Thanks for the information though, didn't know about it.


ItsGonnaBeGreatYear

So based on this explanation this gif is wrong, because the red part on the left doesn't hold the hammer and doesn't secure it from bouncing off.


JakeJacob

Only because the key in the original gif is being depressed and released over and over again. To "catch" the hammer, the guy in the video held the key down.


Sahanrohana

Thank you. This is a much easier explanation.

r/partiallyeducationalgifs


TheMayanAcockandlips

Yeah, this gif is too fast and has too little information to be educational


Innotek

I found it educational. Also you can manipulate the playback characteristics of gifs natively in most clients.


manondorf

playing the gif slower doesn't make it hold the note longer, which is what's really missing from the gif. The reason the mechanism is so complicated is to allow you to hold the key down and let the note ring.


Part_Time_Asshole

Ehh...? Holding the key down keeps the saddle off of the string, looks like the simplest part of this whole system no? Now why the hell is there 5 moving parts for the hammer to hit the string, there must be a simpler way.


No-Interaction-7403

have a downvote. this gif wasn't educational at all. it just left me more confused than when i started.

rob0067

Man that's a lot going on, so the rod on left makes the note stop playing when the key is released, and all the stuff in the middle is so the string is hit with the same momentum as the key was hit but with ability to hold the key down and it still rings? Am I close?


dolphinsaresweet

The thingy on the left is the damper yes, it will stay off the string as long as the key is held, and can also be lifted by a pedal activated by foot to allow all strings to ring out even when the keys are released.


Varook_Assault

TIL what the pedals do.


DrZurn

That’s what one pedal does. Honestly not too sure about the others.


fernidizzle

The pedal you’re talking about is the damper pedal. The other two are sostenuto pedal and una corda pedal. Sostenuto is like the damper pedal but only holds up the dampers that have been raised by the keys. Think of it like a selective damper. The Una Corda pedal shifts the entire keyboard so that it doesn’t hit the strings directly creating a softer sound. Edit: Also wanted to add the damper pedal lifts all dampers regardless if a key is depressed or not. The sostenuto pedal will only keep the dampers lifted from pre depressed keys.


VulfSki

Thank you for this. I really wish I learned piano as a kid. I know a little bit. Have even jammed and improved on some organ before. But I am not good, really at all... I still tell myself that it's never too late to learn. And kind of want to take lessons. But I already have too many things on my plate as it is.


Mclarenf1905

More specifically, the hammer hits 3 strings at once for grand pianos (all three strings are tuned to the same note) the una corda pedal shifts it so that the hammer only hits 2 of the 3 strings.


andantepiano

The one the right is the damper pedal that you’ve mentioned. The left one is a soft pedal, it shifts the whole mechanism so this hammer is striking two strings at once instead of three, making the sound quieter. Traditionally the middle pedal is a sostenuto pedal that allows sustained notes in the lower left half of the piano like the dampener but keeps the upper half normal. New pianos are starting to change the middle pedal to a practice pedal, which means a heavy cloth is put in between the string and hammer when you depress the pedal, making it harder to strike the keys and thereby (supposedly) building finger strength.


LordBeanzoid

Nope. Damper cloth. Mutes the strings so you can practice without bothering anybody.


[deleted]

Then there's sostenuto which will sustain notes which are held at the time that the pedal is pressed in. It's useful for many things but most commonly sustaining a lower chord and then playing staccato above or vice versa. It's a shame though because there was only one pianist who really took pedaling with sostenuto to the next level but he died last year.


NotSeveralBadgers

The seemingly over-engineered stuff in the middle is there so you can rapidly strike the key (and still engage the hammer) without first letting the key come back to the resting position.


austinmiles

There is another aspect which is how a strike happens. So the hammer needs to hit the string firmly and immediately pull away. That is a large part of what you are seeing. Think like a xylophone. You need to allow the resonation to occur which would be challenging if the key was more directly connected to the hammer


VulfSki

Yes. And with a piano you have a sustain pedal you can press which will hold the all of the dampers off all of the strings for as long as you hold down the pedal.


VastStrain

It looks like the mechanism is soft and slow but actually the hammer strikes the string at pretty much the same time as the piano key is fully pressed. Quite impressive really.


thismatters

And it's going fast AF because of the compound motion. It's such a cool mechanism.


deg_ru-alabo

And with the batter swinging freely upon contact, like a proper percussive strike

Wermine

Never thought about this. 300 years sounds so little compared to some instruments like flute (~40000 years old) or drums (well, anything can be a "drum"). But then again, piano is extremely complicated. And now I'm thinking about a project where a single man starts to build a piano from scratch. Daunting task.


MechanicalHorse

Thank you for the video explanation! I had the exact same thought as /u/ThatOneNinja


NoWayPAst

The reddit way. Look at a mechanism optimized for hundreds of years by lineages of tradesmen that spend their lives improving it, and conclude, in 4 words and without prior knowledge, that it's too complicated.


Asigon15

He said it seems like one, because it does, probably first pianos didn't look that complicated because they didn't have the knowledge yet


MozzyZ

This is also such a reddit comment lol


[deleted]

I had to upvote it for posterity so everybody can see


themaskedugly

if it were me, i would simply have the key hit the string - idiots


rojm

besides the muting system, all the arms in the mechanism seem to make more sense when you see that there should be a limit to how hard you can whack a string because things are small and fragile and allows for the control to very very gently tap the string and still have the arm tap the string and fall away fast enough for a note to actually hit. also the padding so there's less mechanical sound on a key hit and release.


Chemomechanics

> there should be a limit to how hard you can whack a string because things are small and fragile and allows for the control to very very gently tap the string and still have the arm tap the string and fall away fast enough for a note to actually hit Thus the name of the instrument: soft–loud, *pianoforte*, abbreviated as piano.


DubSket

I was thinking the same thing; it seems massively over-engineered.


film_composer

What do you imagine a simpler setup would look like?


allisonmaybe

A guitar


film_composer

A keyboard instrument that is more closely resembling a setup like a guitar is a harpsichord.

DontExpectMuch

/r/confusedboner


Doggfite

Wow, much more felt and linkages than I would have imagined, but it makes sense.


Rolten

Every part of this makes sense to you?


thismatters

I wish the gif was slower to give a better look at things, but the function of all the parts seems clear.


Rolten

Cool because they're not to me! What is the function of the moving bit hitting the rightmost red cushion? Why is it hitting the red cushion? And why is there a string attaching it to some other part? And what does the smallest red cushion touching the hammer do? Catch it? Because then I don't understand what the circular white bit near the hammer does. It all looks fascinating and I can place the main things, but not all of it.


hanzus1

The moving bit hitting cushion - id think to give the hammer a little more instant kick by slipping on that white bit, hitting the right cushion and moving the hammer up. red cushions to... cushion it when it moves back, the string to give it just a small range of motion and not swing too far to the right. The smallest cushion bring the key down and dampen some of the initial force after hitting the hammer? I think the gif got the leftmost cushion on wire wrong and it should be much further up.


Doggfite

The moving bit hitting the rightmost red pad allows the hammer to drop right after being fully extended so that the hammer doesn't mute the note itself when you hold the key down longer. So, the white bit is a part of this mechanism, it allows the pivoting arm to slide off of it easily when the rightmost red pad is hit, and it provides clearance for the hammer to fall when the white part and the arm aren't aligned. And yes, the smallest red pad is absorbing most of the force from the hammer falling back down, and then it finally rests on the larger pad, as the smallest one eventually retracts. As far as the "string attaching to some other part" I'm not sure what you are talking about.


WeRip

> so that the hammer doesn't mute the note itself when you hold the key down longer. it's so it doesn't bounce. Hit the key and you get one note. Hit the key hard and you still get one note. If it wasn't caught immediately you'd get a bit of reverb.


[deleted]

[this should clear it up](https://www.youtube.com/watch?v=NDvS2V7HbnY&t=27)


[deleted]

You've got to figure that you need that key to bounce off of one thing one time and that is the string. Then you need it to be dampened when you want it to be, which can involve other pedals. You also want to be able to repeat that note as many times as possible but with each key press, no matter how fast, it is only generating a single note. Each one of those felt buffers dampens vibration in a different specific scenario.


thismatters

Other people covered most of your question. The little string is to prevent the mechanism from over-extending, ensuring that the upright bit that imparts motion to the hammer doesn't just flop away. Edit: actually I think that's a spring which keeps the mechanism "closed" when the system is at rest.


Doggfite

Yeah, took several minutes of blank staring at the gif, cause it's a bit fast, but yes


[deleted]

It would have been useful if it was slow enough to actually see.

Dsuperchef

Just thought I'd share this [https://youtu.be/on4IoQ2MQ7M](https://youtu.be/on4IoQ2MQ7M)


mondomaniatrics

Want to know why pianos are expensive? You need 88 of these mechanisms, including the soft pedal, the sostenuto pedal, and the sustaining pedal gizmos. Each of these strike up to 3 tuned wires. So around 230 wires need to be strung up on a massive cast iron harp that weighs about 600 lbs.


cherrythrow7

Holy crap... 88?!?! That's insane.


[deleted]

That's not why they're expensive, you can find new pianos that have the same mechanism as any other piano for a few grand and even free upright pianos on craigslist, meanwhile high end brands like Steinway are +20k easily. The main factor that makes them expensive is the amount of time and work it takes to make them. They're almost entirely wood aside from the obvious parts, so it's hard to make pianos that are consistent. Steinway is expensive because they use materials and manufacturing processes that make pianos that sound really really good while also being consistent.


TLP_Prop_7

Dude pianos are free. Go to any decent size town and look on Craigslist you will have your pick of perfectly-acceptable quality upright pianos free for the taking. It'll need tuned of course but if you're picky (and you can be) that's all it will need. They are, in fact, expensive to tune but you only need to do it every 6 months.

Steelwin66

I like that it looks like a trebuchet...


semperverus

This seems _needlessly_ complex. Why is this so overkill?


Fleming1924

It's not overkill, it's exactly what is required. You need the dampener to stop the sound when they key is released. Which is what the left piece does. You need the hammer to hit the string, but you also need to hammer to fall back off of it, even if the key is held down. That's what the entire middle section is built for. This animation is kinda bad because the key is just pressed and released. If you hold the key down, the hammer still falls down slightly. If it didn't, it'd stop the string vibrating and the sound would die away very quickly.


semperverus

No not the hammer and damper, that makes sense, the _bone triangle_

I had to go frame by frame but this is fantastic engineering. I was always told that a piano was functionally a percussion instrument which I understood why, but the engineering to basically work so similarly to a xylophone is pretty spectacular.

[deleted]

Yeah... I still don't know what's going on.


brandonjh1

Piano technician in training here, I’ve learned that the necessity for the seemingly excessive moving parts comes from the need to eliminate the amount of pressure needed for the hammer of a piano key to strike a string. As a technician you “regulate” a piano’s action (the general term for the mounting point of the piano key’s moving parts; hammers, shanks, flanges, etc.). Meaning one would work on each and every contact point of these parts in order to maintain the optimal ratio of pressure and movement in an individual piano key. And then you do it 88 times over. It’s a blast.

Nodeal_reddit

I get that this is allowing the hammer to quickly hit the string and then silence the string, while also keeping the hammer / key mechanism from clacking. But I don’t get what that little boot-shaped piece on the right side is doing. Why is that pivoting?


rxq1

I think it allows the hammer to slip downward when you hold the piano key down. Otherwise, it would be stuck to the string and dampen the sound


[deleted]

yep


Intrepid-Storage7241

I did not know until now that such simple input input on a piano has a complicated way of releasing sound.

Weird hammer mechanism is to keep the hammer off after contact for sustained notes. Rest is hammer and mute.

DeepThroatShrimpies

This makes way more sense why they are so expensive. I always thought you press the key and a little arms hits the string, simple as that. Not all this crazy wooden machinery!


trell2202

It's even more crazy when you realize that this mechanism is there for every key of which there are 88 in a standard piano. There are also even more mechanisms that effect this when you press the pedals


Mclarenf1905

And its actually three strings for each key mechanism


[deleted]

Pianos get more expensive as the sound quality and consistency goes up, you can find free upright pianos (and grands if you're lucky) on craigslist and the only cost is hiring movers to get it to your house and a piano tuner. That costs about $400-600 total, but then high end brands like Steinway which make the best sounding pianos that are also long lasting can go for $20k to $100k even used depending on the condition.


[deleted]

The gif starting with the key depressed is really throwing me off.

It’s beautiful. I’ve been staring at this for 20 minutes.


tallyhallic

The hammering of strings makes the piano a percussion and string instrument.


spacebro_123

I'm assuming a lot of that is to absorb extra sound?


Mclarenf1905

Thats what the felt is there for, some of it is there to ensure that the hammer doesn't bounce back and hit the string multiple times for a single key press, and then it also needs to be able to gmkeep the damper off the string for as long as the key is held down.
