Let me introduce you to the OPUS 102.

[Linked Image]

It's a 3m grand piano (102 keys) built by Stephen Paulello in France.
http://www.stephenpaulello.com/

It seems that it has a very rich tone and of course it is very powerfull.
I never heard one by myself though one has been sold to the pilarmony of Paris.
It cost 160 000 euros, not the most expensiv piano.

It uses a few tips and tricks and strings are made by Stephen himself.

Anybody know the design philosophy behind not cross-stringing?

There is a comment on his website.
You probably can read it because there is an english version but basicaly he said that he does not explain why he did that because it's too technical.

These ideas are not new. Parallel strings date from the origins of the piano, keyboards have already been enlarged and Broadwood once produced barless iron frame pianos. On the other hand, bringing all these elements together in the same instrument has never been undertaken.

By the way 3 have been sold to the Musikverein in Vienna.

Why is it that grand pianos, normally, top out at 9'?

Thaks for sharing GR20.

The Opus 102 has been around since December 2015, and the sound continues to mature with each new recording. It has gained body and color since my first hearings. I find it a most remarkable instrument - indeed,quite possibly a pardigm shift in piano making. I hear it doing things that I have heard no other piano do.

The second recording is by David Bismuth, and is from the album "Beethoven et ses maitres" - mostly Beethoven, but also Handel and Haydn. If you want a better recording of the 12 songs on this album, you can hear it without that Youtube glaze at much better fidelity on Spotify. You can join for free in about 30 seconds, With good headphones it will be an ear opener..

https://www.youtube.com/watch?v=JMSwiuVrUzE Body and Soul, Franck Avitabile also. Does it sing? I have never heard a piano carry the melody like this one does. Gorgeous playing.

https://www.youtube.com/watch?v=_TIDxZ_1TFo Got bass? Ragin' Beethoven

GR20, the piano is more radical than you know - no ribs, no downbearing, bridge agraffes of Stephen's own design, a single continuous bridge, barless plate construction, 102 notes, nickel plated soft iron wrapped bass strings, and hybrid stringing.

Does Stephen Paulello make 170~180 cm size grand piano?

I looked at the website and found a Miniature grand piano pdf file but there is no size info inside.

It seems that they do custom pianos.
I found a french article and they said that the price range is between 85 and 170 000 euros.

By the way i sent them the question and here is the answer :
"Nous proposons 3 modèles de pianos: 3 mètres, 2m20 et 1m90. Tous ces pianos ont des claviers à 102 touches et sont fabriqués selon la même technologie. Pour l'instant, hormis l'Opus 102, il n'y a pas de pianos en stock car chaque piano fabriqué a déjà un propriétaire. "

They offer 3 pianos, all with 102 keys, which share the same technology (3m, 2m20 and 1m90).
All pianos are reserved, there is no one available (except the OPUS).

The last time I communicated with Stephen Paullello by email several months ago (I have been buying his wire and bass strings directly from him), he told me that he was in the process of constructing his first 170 cm. grand. It is supposed to be 97 notes. I don't believe it will have 102. He has been building an 88 note 2.87 m concert grand for many years, you can find many videos of it on Youtube.

He is a very small builder, and essentially builds the pianos on commission. He's not a flash in the pan, he has been doing this for close to 30 years. I believe that part of his business model has been to continue to rebuild pianos for clients all along.

Mark, there has been one other piano maker who built pianos with a barless plate, and that was Broadwood. Their piano was overstrung, as compared to Paulello's parallel stringing.

I read both websites, Paulello's and Barenboim's, I couldn't find any objective information regarding the design.
In theory this is what I believe to be the reasons behind the design:

1) Stability: Commonly the sharper the angle of the crossing-string, it is likely to be more unstable.
2) Sound-board's energy reflections: The energy of the string it is transfer from the bridge to the soundboard, that energy it is partially dispersed, consumed and reflected within the soundboard. When those reflections comeback close to the input area, it favors sustain in the piano. Perhaps this design creates a more uniform direction of the soundboard reflections.
3) Pressure on the soundboard: Very often at the upper part or tip of the treble-bridge, there is less pressure on the soundboard as that string-section reaches the end of the bridge, versus the middle section where you have consecutive strings applying consistent pressure across that section . This sometimes leads to a weak or less defined tone in the upper section of the treble bridge or break. Therefore sometime more mass is loaded into the bridge to improve the energy transfer. I imagine having one bridge, it will equalized the tension across, improving energy transfer to prevent weak or less defined tone.
4) It may increase the speaking length (vibrating and functional portion of the string from the bridge to the termination of the string)

Keep in mind I am just making a case for this design, it will take to have a side to side comparison with similar quality pianos in order to confirm the advantage or disadvantage of this design.

If he would demonstrate a 5-foot piano, that would show whether he really knows his stuff!

A flat-strung piano will not have as close coupling of the tenor strings to the bass strings when the pedal is used. That makes an audible difference, although most people will have to listen for it to notice the difference.

I'm dubious of your assertion. Why?

To me it seems obvious: the tenor and bass bridges are farther apart, therefore, less coupling. And you hear the result best when the dampers are up to allow sympathetic vibration.
