Great video. No talk, just animation. Very easy to understand. Much thanks to you. I hope you could make another video to explain how the piano pedal work.
They lift up the damper, with the exception of the 3rd pedal which moves the hammer slightly to the side so it hits 1 string instead of 2 or 3(creates a softer/mellowed sound). That's a simplified explanation if he doesn't make a video :)
really great animation of the concept. i am studying ME (mechanical engineering) in germany and i plan to take part of the ani for my presentation in english class. of course first of all it sounds a little bit odd to mix music with ME, but after watching this clip you will know why the piano is one of the most beautiful masterpieces of maths and physics, i.e. ME. :) thanks for posting this. your edit is also a masterpiece. :)
This was perfect and just what I needed. One of my keys on my Hailun 198 doesn't always reset properly. This video has helped me to believe that my problem is likely something to do with the jack not slipping off the "knuckle" on the hammer properly at all times. I guess as the piano ages some of the felt gets compressed and things need to be adjusted. I have humidity control in the piano so I think I'm going to do a bit more research then pull out the action and have some fun. (I've also got some Teflon powder that I obtained from my previous piano tech guy that I can make use of). Thank you for this video and the great animation!
Thank you. I understood things much better thanks to your animation. The excellent book I am reading "The physics of musical instruments" still cannot rival what you shown here.
I've never been classically trained on piano, I just play by ear... So it was never thoroughly explained how intricate a piano really can be! This is really cool actually
Truly great animation! Looking forward to part 2 with the distinctive repetition steps.: The animation is short of the repetition motion, which is very specific to a grand piano action, and basically distinguishes it from an upright piano action. The animation does not show the effect of the contact of the wippen repetition lever with the drop screw. Nor does it show the upward motion of the hammer to the drop screw limit, after its release from the check. So, the jack is positioned again to repeat its propulsion motion even though the hammer is not back to it's rest position.
Excellent animation of the action of piano key and its mechanism. It would be nice to have some narration explaining the importance of the Repeater Action and its importance to the modern piano, but this is a very useful illustration of the workings of a piano.
At 3:11 , the screw against which the jack should hit to roate, is too high. This is what makes the jack rotates, and so that the other part can catch on on the cylinder on the arm of the hammer.
In the resting position, the hammer shank must never touch the hammer rest as this animation shows. The only contact between the hammer and the wipen is the knuckle (or "roller") on the repetition lever. In the resting position, there should be a space of 1/8" between the hammer shank and the top of the hammer rest felt.
its really great to se how digitalpiano maker improve to simulate this real pianoaction. feature like escapement-let off, halfdamper function, string resonance, multi-sampling. real piano is best
2:11 so I think the small, brown ring at the right hand side is how the "let off", also known as "escapement", is done... it lets the hammer hit the string, but immediate allow for the hammer to drop back a little, so that it won't hinder the free vibration of the string. It also has to work well if the piano player release a little bit and immediately press on the same key again, to give repeated notes... to see the interaction of how the "let off" happens, a video is here: ua-cam.com/video/01DBtig_Fgw/v-deo.html
Very good video. I'd like to ask you if it's possible for me to use it for an exhibition at my school about the piano. Thank you very much for your attention.
This animation is awesome, but I have a question. How do the foot pedals affect the mechanical functions of the piano? Do they control the damper in some way, or do they control the strings in another part of the piano?
Jarod Cromie The foot pedals ensure that if you press the right pedal the dampers stay in a high position. So the dampers are switched off. If you press the left pedal the dampers will shove a little bit, so they mute not all the strings of that tone. You know that most of the tones have three strings.
The damper (right) pedal lifts all of the dampers off the strings, allowing the notes to ring. The una corda (left) pedal moves all of the keys slightly in one direction so that the hammers only strike one or two of the three strings per key. The sostenuto (centre) pedal is typically found mostly on grands. When it is pressed, all dampers currently risen will stay risen, and those notes will continue to ring, but any new dampers will not rise, and their notes will not ring. On an upright piano, the centre pedal can move a piece of felt between the hammers and strings, allowing the piano to sound quieter. Does this help?
These springs are also a problem in regulation because one spring performs two functions. Changing one also affects the other, also when it is not needed.
This is the presentation of the English key action mechanism. But what about the Viennese key action mechanism? Pianos built with this action are still in use.
You are absolutely right. Do you know someone who can do everything and do everything at the same time? Maybe I'll make that animation in the future, but I can't promise you anything!
Really great animation! But unfortunately I miss the part that explains how the hammer can be triggered so fast with only a little movement by the finger
+tofol cano The top of the jack (tender) presses quickly against the circular felt (knuckle) on the hammer shaft (shank) near the pivot point (hammer flange). Hope this helps.
casio GP-300,400,500 is now most simular to real grand action. the World best grand piano maker-bechstein, produce ther keyaction, also affordable price compare to other brands
Excuse my ignorance, I'm not completely clear on this. Is the jack responsible for accelerating the hammer in an explosive enough manner to hit the string hard enough to produce a tone even when you're very softly and slowly pressing the key?
It seems so. But the possibility must be for the hammer to hit the string both softly and hard. That's where the name PIANO comes from, an abbreviation of piano et forte, 'soft and loud'. It takes a lot of machanism to make that possible.
I'm still not clear on what purpose the backcheck serves. Yes, it slows down the downward direction of the hammer, but why is that done? The hammer is going to return to the original resting location anyway. Thanks for any explanation!
The first slow down the of the hammer, is for when the key is pressed again quickly. The distance to the string is then smaller and can be played quickly.
@@Hoeishetmogelijk I don't understand anything of what you said D: Everything I said was 'no offence' :D pls explain why no spring?. It's also element of mechanism, you cannot skip otherwise it's not fully explained.
So we pulled the action, went through these individual parts one by one and STILL can't figure out why C below middle is clicking when pressed down. There's nothing that's fallen under it. And it only happens when the action is inside the cabinet, not when it's pulled out. *heavy sigh*
Is the part of the key that catches the bottom part of the hammer as it falls back to resting position necessary? If so, what is the reason behind that?

who ever created the piano is a truly genius
Victor Valenzuela My roomate
Bartolomeo Cristofori 'created the piano'. I don't know if he was a 'genius' though... He kinda came off as a jerk to me.
Well you see, there were MANY other key instruments before the piano. Piano is the best though :)
there is no much philosophy about piano and the keyboard instruments in general, you just connect the hammer to the key and make it hit the string
You're right. With one string you can not do so much, but with 88 the philosophy will come alive!
Hoe ishetmogelijk yup
>Someone makes an entire 3D model of how a piano key works
>Animates it
>Breaks it into each individual piece
The audience: LOL THAT FINGER THO

Side note: each key has 2 or 3 strings, with the exception of some of the lowest notes, of which some only have 1 string.
really great animation of the concept.

It's insane how someone created this so complex
And that 85 times!

Right. With the action as shown here the whole double escapement principle is pointless.
Excellent explanation thanks

Yes, you are right. However this is only an animation...
It's mechanism is complicated and well engineered . Idk why they did not invent automatic rifle early on.
Awesome!
Exact wat ik nodig had!
very good and thank you.
Love your videos
THE BEST!!
I thought that when you pressed the key it just banged a string. But this is much more intricate than the crude mechanism I was imagining
I hope you learned something from it and enjoyed it!
Cool animations bro
well done

Nice playing sausage!

Does this help?
Good looking graphics. Only: it wouldn't work because the repetition/escapement spring is not shown or mentioned.
Yes, you are completely right. The problem is that a spring is very difficult to incorporate into an animation. Call it convenience...
These springs are also a problem in regulation because one spring performs two functions. Changing one also affects the other, also when it is not needed.
I like animations
Zbrdast good learning
Now please make a video on how to understand this one.
So bassically a hammer is beating the string to give note by pressing a key
Yes, that's all!
Thank you! But who is the pianist and what make is the piano? Lovely playing and an entrancing clear sound.

Now dont ask why grand pianos are expensive
Really great animation! But unfortunately I miss the part that explains how the hammer can be triggered so fast with only a little movement by the finger
Yes, you are right. I forgot that part. Perhaps later?
At 2:23 By means of the lever system put by each other piece, the hammer picks up speed.
The jack pushes the shaft of the hammer where the round thing sticks out, pushing the hammer up really fast.
Excellent graphics, but it doesn't show the working of the repetition lever which is the main feature of the grand piano action.
Nobody is perfect!
@@Hoeishetmogelijk No offence intended. It would perhaps be to complicated and no one else seems to show it anyway.
The piano is a monster that screams when you touch its teeth.
But why does the hammer jumps straight up when the key is pressed?
+tofol cano The top of the jack (tender) presses quickly against the circular felt (knuckle) on the hammer shaft (shank) near the pivot point (hammer flange). Hope this helps.
Cobrun Sells thanks
Put some tacks on the hammer see how it sounds.
Mooi.
Animatie van jou?

Excuse my ignorance, I'm not completely clear on this. Is the jack responsible for accelerating the hammer in an explosive enough manner to hit the string hard enough to produce a tone even when you're very softly and slowly pressing the key?
This is a mechanical engineers wet dream :)
Why so complicated?
what's the point of all the intermediate levers to swing the hammer?
its just a simple up and down motion in the end right?
It seems so. But the possibility must be for the hammer to hit the string both softly and hard. That's where the name PIANO comes from, an abbreviation of piano et forte, 'soft and loud'. It takes a lot of machanism to make that possible.

The first slow down the of the hammer, is for when the key is pressed again quickly. The distance to the string is then smaller and can be played quickly.
@@Hoeishetmogelijk Yes, I can understand this now. Okay, that seems sensible now that you explained it.
Where is the spring??
It is very difficult to animate the spring. That's why I left that out. maybe one day I'll try my best to implement that.
Oups, I forgot to add spring to mechanism, let just create a creepy finger, nobody'd see.
Yes, you are right! The key is not pressed without a finger. I did not forget the spring, but that makes explaining how it works even more difficult.
@@Hoeishetmogelijk I don't understand anything of what you said D: Everything I said was 'no offence' :D pls explain why no spring?. It's also element of mechanism, you cannot skip otherwise it's not fully explained.
So we pulled the action, went through these individual parts one by one and STILL can't figure out why C below middle is clicking when pressed down. There's nothing that's fallen under it. And it only happens when the action is inside the cabinet, not when it's pulled out. *heavy sigh*

@@Hoeishetmogelijk A lot of good it did me, ha! :-)
3:21 WHERE'S MY HAND, AND MY FRIEND?
There is only one key, so you need only one finger!
would've been easier to put a xylophone upside down and have a bunch of seesaw mechanisms under it
Perhaps, try it!
That's the most unproportionate finger I've seen.
Yes, it is not perfect.... But is plays without pianist!
1:03 OUCH, MY FINGER!
Is the part of the key that catches the bottom part of the hammer as it falls back to resting position necessary? If so, what is the reason behind that?
There are some reactions below that will answer your question.
0:35 damn that finger tho
Xxbenny gamesxX you need a vinger to play! It's not automatic!
I miss the SPRING¡
Yes that's right! It is very difficult to process that in an animation. You can just call it 'lazy' from me.
