Upright Piano that Sounds Like a Grand Piano

Overclock your upright piano with this small trick!

[jonidrinksonionade]

Piano manufacturers don't want you to know this one simple trick!

[ConstantThrowing]

Man what a clever guy. This is the essence of invention here. Simple solutions to seemingly complex problems.

[bengieg]

"don't buy an upright you can't you will never be able to learn advanced piece because of gravity and how you can't hit the notes repeatedly"

Japanese guy comes solves the problem with a little metal string.

[Hsuperj]

Wow i finally know why its so hard to do fast repeated notes on an upright

[elitefitrea]

It's cool to see continued refinement on the piano after hundreds of years!

Thank you for this historic, needed improvement to upright piano action! Kudos to Yukimitsu Fujii. Serious pianists who can't own a grand, can now enjoy the same grand repetition speed in uprights! Many homes have no space for a grand. Many pianists lack the financial means to afford the more expensive grand pianos. Uprights pianos equipped with these two additional springs on all 88 keys are the greatest vertical piano action improvement to date!

5:24 *plays c chord* this sounds totally different :0

[globalmess]

its for when you need to hit the same note 14 times in one second and moonlight sonata was a great example of that

Thank you for an excellently made video. A couple of things that I hope may help:
1 I think the video should be renamed "Repeats more like" rather than "Sounds like"
2 Bechstein put a similar idea on their upright models I to IV and 6 to 9, made mostly from about 1890 to 1920. These work well but they add a loop for the spring to connect to, which is a bit cumbersome when you want to work on them, and also usually means that the check has to be regulated so the hammer checks much closer to the string; otherwise they tend to double bounce. However the Bechsteins sound very warm and rich and restore well.

Thanks again for taking the time to show us this. If you're ever in Oxford UK please do visit us. Best wishes, Marcus Roberts

This is very interesting. As a piano technician, I believe that He can make major difference in piano manufacturing. I could imagine many piano manufacturers using his new design for an improved functionality of an upright piano, whose action design has remained mostly the same for over a century, excluding earlier birdcage actions.

[Wayman_Simmang]

the man is a genius, , wonder why someone else hadnt already discovered this.. congrats to this man for his hard work!

Very interesting. It seems as if this little innovation should be used by all piano manufacturers.
I do hope Mr. Takumi is getting credit for it and financially benefiting.

[matthewrichards]

I think this is a good idea. There have been springs added to upright actions to improve repetition, but this system in the video looks good. Innovation like this brings something new to the table

[johnkerr]

Interesting, thank you. Summary:  2 springs added.   First spring returns lever faster to allow for more notes per second (14 with vs 7 without).  Second spring  pulls hammer off strings faster to make the strings sound less muted (and more like a grand piano).

People's intelligence, ability to innovate, never ceases to amaze me. Well done.

[ChristiRich]

I want this for my upright. Bring it to the United States. :-)

[lifedoom]

3:23 bold of you to assume my teacher is rich

[joshbonner]

There’s an easier way! Put led weights on the tip of the hammer tails, I’ve tried this and it works very well

[raffaelesantabarbara]

I hope Mr. Takumi will get all the attention, recognition, and success in the world for his improvement to upright pianos.
