Piano: *plays by itself* Audience: Everything is normal.

As a piano technician, I can say this is an excellent diagram of the piano action. I will use this in the future!

Pianist: Leaves lid open Dust: I’m about to end this piano’s whole career

Now I understand why pianos is *so damn expensive*

thanks tom and jerry already thought me this tho

Professional presentation.

Underrated channel you have over here

Its crazy how complex the key thing is and that are 80 of them

I had no idea of how complex a piano really is. You animations explain all of the workings with extreme precision. Quite simply, you are amazing as I have watched many of your animations...I really enjoy them!! Thank you!

This is exactly what I am expecting from a "how it works" video! ❤️❤️

I have never seen this much accurate, clear and crisp animation 😮. Very well done

Jared, these videos are really the two best I have EVER seen explaining the piano. I can’t praise your work highly enough!

I am a 30+ registered piano technician professionally, and this video is spot on. Well done! (Where were you 30 years ago when I was just learning??)

I knew all of this from before, but I'm glad that there's finally an animated educational video out on KZfaq for everyone to see! Great job, Jared! Keep up the good work!

Can you please show us stupid creatures how does a printer work? Btw great videos!

This is why I love the piano, such a beautiful and graceful instrument with complex mechanisms designed to make a wide variety of soft and loud sounds.

4:03 how cannot anyone retain himself from smiling with that music?

So is a piano just a giant guitar?

Fascinating! I also watched your Part 2 video and equally fascinating! It would be great if you could add an explanation of how the repetition lever works.

Thank you! This was so informative. I just got my first acoustic piano and I’m learning how it works. I really appreciated the terminology and demonstrations.

Jared, this is so well done!!!

Been playing piano for 10 years and still counting and I had no idea about all the detail within the hammer mechanisms! Thanks for clearing it up!

Jared Owen. What a very fine teacher and animator you are. Thank you for your service to humanity!!

Wow! Fantastic animations and great explanations! I will definitely be showing this to my piano students!

Jared, Your videos are video's best! Thanks!

Thanks for teaching me something New! And AWSOME VIDEO!!

Wow...Great job. I can not imagine how hard you worked for making it.

Such a vivid, optimum and to the point presentation. Just loved it.

wow! so much work for this video!

BEST ANIMATION CHANNEL EVER and so do the explanation too, omg you are a kind person thanks for sharing the Information for curious creatures like me about how this world works

Excellent video, so clearly explained and great graphics. Thank you!

I just discovered your channel and I'm in shock at the incredible amount of work you do for these videos, instantly subscribed

Great animation , I've always been a fan of yours. You also explain in a great way , so keep up the good work

Amazing animation work, mate! Not only it is very detailed but it's also explained very well. Keep up the great work.

Great video, great job on explaining each part and great animation!

Mad respect for you because you actually put the right notes on the piano

Wow! you learn something new every day!

Thanks for this video! I only knew the basis of how the piano works but you explained it so quickly and goodly.

Your video are so good quality that you've earnt a new subscriber! Great job man!

These are great educational videos. I had no idea there were so many different mechanisms involved in playing single notes!

Very nice video, I can only imagine the amount of research you did, these aren't simple instruments! One thing that might interest you for the video of the pedals is that there is a new experimental fourth pedal that is called harmonic pedal, might be worth taking a look at it.

This video was so helpful, thank you mate! Keep up the good work! :D

Short, clear and instructive. Thank you

Great video. Keep it up n thank u for the great knowledge

Thanks Jared! Awesome job!

Some really quality content here, Jared!

Jared, I love your animations! How could anyone give you a thumbs down? Anyway, good job!

Very well done animations, and a great explanation that everyone can understand!

This amazingly educative. Thanks a lot, you gave me what I really wanted!

Very nicely done, Bravo !!! just a small downside: it lacks the extremely important spring between the wippen and the repetition lever This spring gently raises the repeater lever when the key is released and therefore the hammer rises slightly, allowing the Jack to reposition itself under the hammer roller. this is what is called (wrongly!) the double escapement, and it allows the note to be replayed while the key is not yet fully raised It is a wonderful, French invention of the 19th century, which the upright piano does not benefit from !! I have put it as a link on my website of piano tuner , thanks !!

This is very well made. It's missing few things, but you talked very well about the most important. Nice job !

Brilliant video Jared. Thank You.

I've been playing the piano for eight years. We used to have a classical piano in our house. It was about 100 years old. My piano was so broken and it sounded terrible. We put that piano in my mother's friend's house. I have a yamaha digital piano right now. But the grand piano is one of the things I want most in my life. I've played at a concert a couple of times before, actually... And it was a beautiful feeling...

This is amazing, thanks for sharing with us!

Thank you for making these videos, they really inspired me. :-D

This animation was amazing, man. I'm so happy to being able to access this quality of content because I learned how to speak your language.

Yo mate, great animation and content. Thanks for your video

Very educating video, Underrated channel who deserved more attention

THIS SO COOL, JARED! Thanks for educating me.

Excellent video. Thx for uploading

Brilliant explanation. So cool. Thank you very much for sharing it.

Great animation and break down, always wanted to know all these little pieces and especially how they function if needed to be replaced.

as a pianist with perfect pitch I thoroughly appreciate the fact that for the opening and closing animations (where the keys were shown moving), the correct notes were actually being played on the piano

The explanations are great and the animation even greater! Well done.

Precisely what I was looking for. Thanks!

I would love to see you revisit this subject and go into more depth. On your newer videos you dive deeper. For instance, though you explained the the wippen, I can now see it in my head, but still can't quite break it down as much to what individual parts do within it. I see this is an earlier video than the half-dozen I just watched (and then subscribed). Your newer videos put that show "how it's made" to shame. Regardless, whether you do dive deeper into this, keep up the great work.

Amazing, love this work. It must took a lot time to do this

What a great piece of animation, Jared! Very instructive! I've often said that if I could do it all over again, I'd learn to play the piano. It's the most versatile instrument on the planet. There is no style of music that you can NOT play on it. You can't say that about any other instrument.

Brilliant work. I know how hard it is to animate these, and you made it seem effortless.

This was excellent. Thank you!

Jared this is awesome! Very comprehensive look on a grand piano. I just found your channel because I am researching some material to teach to young students at a small art school. Do you mind if I share some of your videos with my class?

Magnificent animation! 👏🏻👏🏻Thank you!

very clear, and easy to follow, just what I needed, thanks.

Absolutely amazing!

nice visualizations, good job!

My daughter and I were talking about how the pianos work, and came across this. This was perfect! Thanks for sharing

Thank You So Much. Amazing Tutorial

Thank you very much for your fantastic video ! What a work ! I am amazed ....

It is awesome!

Thank you so much Jared! Such a neat and on point tutorial!!

Outstanding work, thanks

Very cool! This topic is perfectly explained

Fantastic video, thank you so much!

i love that theres clapping but no audiance, this is a great explanation it helps alot

It's so amazinggg!

Great modeling. Very well done

Wow wow wow!!! You are amazing!!! Thanks for sharing this video!! I can show this to my students to explain how piano works! I’m a pianist but also a pilot. Can you do how the airplane works? Single engine (propeller) airplane would be fun!

This is an amazing video. Honestly

This animation is awesome! As a person who does play piano, thank you so much for the educating =D

Animation is so cool and thank you for the lesson 😊

We appreciate your hardwork

so good! finally i understand. thanks a lot!!

I never knew till you explained. Excellent man!!!

What an excellent, easy to follow video! My kids asked how pianos work and this us what we clicked on. They loved it. Jared, your name sounded familiar--then I saw your picture at the end and was like wait. I know that guy!! Haha, we loved your work and will now go check out your channel!

4:00 just made my day.

So great man...

What are marvel of engineering the grand piano is. Genius design.

Thank you so much Sir for this video...

Wow! Tremenda explicación y tremenda animación. Excelente 👏👏👏

Addition: The part where the shank meets the jack is called the knuckle. As the jack pushes the knuckle the shank (the long arm leading to the actual head) is raised, thus lifting the hammer. Fun fact. the hammer is actually "thrown" into the string. Jared briefly mentioned this, but it is important. If you press the key very slowly the knuckle will never leave the jack before the highest point is reached (called the "let-off", more on that later). Pressed in this way, the hammer will approach, but never actually touch the string, before falling back on the down side of the let-off. You'll further notice the let-off will occur -before- the key press bottoms out on the board. During a normal key press, the hammer only reaches the string to the point of contact momentarily because the velocity of the press punches the knuckle with sufficient force to throw the hammer all the way to the string. The hammer can then return to rest, still raised by the repetition lever, but resting off the string. The let-off position is very important. A properly regulated piano will have the entire key line regulated to have the let-off in the the same position across all keys. Artist preferences notwithstanding (they can be a finicky lot), the let-off is normally about 1/16th in. off the string. The "cylinder" Jared mentioned near the back is called the let-off button, and that is the point where the let-off is adjusted per-string. A nearly universal technique for adjusting the let-off involves a magnetic strip of precisely the requisite let-off depth that is placed on the underside of the strings where the hammer line makes contact. The strings are metal; the strip will stick to them. The let-off button is then adjusted to the point where the hammer just-touches the strip. Once the strip is removed, the let-off is now-set to that depth (and you can move on to the other 87 keys; oh' joy). Finally, as part of regular maintenance you may wonder how often regulation has to be done. Depends on the piano, how often it is played, how often is is -moved-, etc. Things loosen up, get kind of janky, etc. I have my grand tuned twice a year, and regulated every 4-5 years. Still amazes me how awesome-sauce it feels the first time I play after both have just been completed. (of course, there's a lot of other things done during regulation, hammer shaping, sled-waxing, etc.).
