Hi and welcome to and I'm Robert Estrin, your host. Today's question is what is the biggest piano in the world? All right, this is a great question and you're going to be surprised at the answer. But at first I want to give you a little back story. Of course Baby Grands are around five feet and Grand pianos are around six feet. You've got finally, the Concert Grand nine feet. And the largest production piano in the world is the Bosendorfer Imperial Concert Grand at nine and a half feet long. Is that the biggest piano? Not by a long shot.

The biggest piano I have personally played was a 12 foot piano made by David Rubinstein. And it is a wonderful instrument. In fact, he built two pianos; an eight foot piano and a twelve foot piano. And they're remarkably good pianos and particularly considering that those are the only pianos he's built. And he just didn't parts from other manufacturers, which is typically the way a lot of people or small manufacturers - they'll take a plate from one company, and axom from another company and do some tweaks to the scale design. But no, David Rubinstein, he produced these pianos completely, the plates, everything. And they're very nice instruments and a 12 foot piano has a very big sound. But is that the biggest piano in the world. Believe it or not, no.

In fact, in Poland Daniel Czapiewski make a six meter piano. That's almost 20 feet long. It weighs more than two tons. Can you imagine such a thing. Now, I haven't had the opportunity to play this piano but it is remarkably large. I can't even imagine what it sounds like. Now, does this mean that the bigger the piano, when you get that big, is it going to be better? Not necessarily. There's a lot to the physics of the sound that's involved. I would reserve judgment on that piano until I played it, but you have to figure there's a certain amount of energy your fingers could impart to a hammer to a string, and just a certain amount of energy that that string is going to exert on the soundboard with a sound board that immense. The question is how much energy does it take to get it to vibrate. I would love to try that piano.

But at this point, the biggest piano I've played is David Rubinstein's 12 foot piano, and that is quite an instrument. And the largest production piano, the Imperial piano, The Imperial Bosendorfer, nine and a half feet.

Thanks so much for the great questions. keep them coming in. I'm Robert Estrin here with and

what is the most expensive piano in the world? is price in line to the quality of sound they produce? thank you!

Bigger isn't necessarily better beyond a certain point. After all, human hands and the energy they produce is only within a certain range. Also, the laws of physics of sound call for specific requirements in order to produce the desired sound. Otherwise we might have 30 foot pianos!

While waiting for an organ lesson, I sat at their grand Fazioli piano. I found the keys required a great deal of strength. Do you know if this is typical of Fazioli pianos, or maybe all grand pianos require more strength than an upright?

On a different subject, I would like to contact you by email, but when I click on it on this page, I get the message: Could not perform this operation because the default mail client is not properly installed. I have a question regarding the felt of my upright Yamaha and would like to send you some pictures. I don't think it is installed properly, but the piano tuner did not think it is a problem. Thank you.

You are right - grand pianos generally require more strength to play than uprights. Fazioli pianos do not have unusually heavy actions.

Please email me at That email address definitely works.

That's quite a story - thanks for sharing!

Have you ever played a Fandrich and Sons 212 cm piano? How would you describe the action? This is a piano made in Stanwood, WA by Darrell Fandrich.

I have not played any of the Asian pianos that Darrell Fandrich modifies, but I would be interested in trying them.
