the usual blend and distortion is gone! the clarity creates such separation, the piece sounds like it performed on 2 pianos. well played too.

Knight is superb, and oh what sound from this piano!

Im so happy there will be more than one of these things in the world. The sound of the Alexander piano should be the gold standard of any concert hall.

This is what inventors do they think outside the box great job. I am working on Off the Grid technology self-looping Energy Systems. The world needs Off the Grid technology the grid is a form of bondage. Think about it if the grid goes down everything you rely on comes to a stop. The dangers of the electrical grid.

nice keep us updated

Dont go so fast!!!

Everyone's all gangster about this Piana until it's moving time! 🚛

Used too much pedal for my liking but otherwise great performance and awesome sounding piano Reason for wanting less pedal: I can play the original 578 on the organ, and when you cant cheat with a pedal it makes a lot of it harder to play as you have to individually hold several fingers down for those notes to sustain while still playing with other fingers in the same hand. Very challenging for most pianists, but the result is a much cleaner and more articulate sound, characteristic of J.S. Bach. I don't mean to be a snob but I figured I would explain my reasoning, and as with any performance the artist is free to interpret the music how they like.

I wonder if it would be even possible/feasible/useful to build a new model, which has extend the lowest notes by 9 more additional keys as in the *_Bösendorfer Imperial_* 97 key piano and how those additional keys would sound....

You are a genius alongside those of Edison and da Vinci. It's incredible that you succeeded. You should have your own factory and compete with Fazioli

I would like to own that thing just so I could call a piano mover and get a quote on moving it, and then watch their face as they roll up and see the thing.

The more pronounced bass really works on this piece. More so than the ragtime piece or any of the other popular classical pieces Part of that I think is that the piano player knows how much he can push those notes.

The bass is a bit overpowering at times. I’m not sure how much of that is due to the piano and how much of it is just the fact that we’ve all been conditioned to hear this piece with a different EQ so to speak. The notes themselves are very impressive

wounder if anyone has asked for you to make more ?

As someone else observed, it's unfortunate the upright isn't in better tune. Having said that, the difference is still obvious, and staggering. Well done.

No words. Breathtaking. Thank you.

This is truly an incredible sound from this piano. Many grands do not have this kind of tone!

have you done a db level on the piano i used to work on pianos and pipe organs back in the 80s and did the lowest notes have copper windings and how many strings in the last octave per note and did you tune it yourself

I hope minimum 300k for you for this order

I'm in a New York state of mind with you.

Congrats on the nice set-up you have worked out. I like to see young people with the ambition and determination you seem to have. Your hard work will pay off and you will continue to succeed

Interesting interpolations into well-known score. I especially like the de-tuning of the low A, to A-flat, since low A is not used in the piece. Thank you for making the effort to travel and give this piano the attention it deserves!

Well done.......can't wait to see more of your exciting updates xo

I love Piano No. 1, and am now trying to keep up with improvements to it. Trying to make sure I have seen all your past videos.

Incredible space for a legendary Mann

Got another steel beam!

I helped move the junk upstairs!!

I love the height of the fallboard. A good reader doesn't look at the keys when he reads, and it must be an intoxicating experience.

Good choice of music, although I can't tell if there is a damper problem--OR--a pedaling problem with the pianist. It does feel as though one is "wrapped" in sound. My hat is off in the most decisive manner to the builder on a stunning job. The pianist treats the bass with great love and respect, since it hardly needs encouragement! She is wise to keep the tempo down in the octaves. Even over a computer speaker, I hear the richness of harmonics. I doubt that I will get to New Zealand, but I would love to hear and play this instrument.

I wish I could like this 1,000 times. Thank you, Mr. Mann for having and executing your vision of this amazing instrument, and Mr. Knight for your lovely playing. Points for playing my favorite composer too.

Great playing by Gilderoy Lockhart

As the instrument is so long, for the benefit of the performer, have you examined a tone chamber, perhaps shaped like an old-school acoustic feed horn, under the piano to channel sound towards the performer. Then again, perhaps instead let the performer deal with things as they are. Instead there might be another panel attached beneath the piano, a mirror of the lid to further direct sound in the same direction the the lid already does. You may surely at times have asked yourself, "what have I got myself into". It seems that you were too young to suffer the notion an older person might, that the task was impossible and instead went with it. As for audio recordings, would a custom pressure zone microphone into one channel, maybe positioned on the floor below the sound board add anything that a scatter of mics would not. If you have not already heard of it, look up Decca Tree. It is a miking system developed in the times of early stereo recording of large orchestras as well as having individual mics for instruments and a skilled mix desk operator.

What a sound! I noticed in another video you said it was too bright. I like it bright.

Wouldn't it be great if some music manufacturer like Yamaha, Korg or Roland sampled This piano's full range of sound and programmed it in to a portable keyboard.

Beautiful! WOW! A truly clarion sound! Rich, clear, vibrant, yet minus that subtle "buzz" often heard in the bass notes.

Amazing!

Ok, at first I was like I can't tell the difference. Then I listened to other renditions on other pianos and now I can definitely tell the difference. They Hyperion seems more present and more genuine and richer sounding. Not sure how else to describe it, but it sounds amazing.

Sounds like a piano.

Sounds sorta like a piano

I hope Martha Argerich comes to perform on this amazing instrument!

yup, sounds like a piano, not sure what I was expecting

Oh, please play Rachmaninoff piano concerto no. 2!

OMG what an amazing work! Fantastic project. LOVE the sound of the bass. You deserve a medal. Come and restore my Bechstein grand!

Nice play v impressive

Sou principiante. Qual é essa música? Te acompanho do Brasil.

Breaking a string on that piano could be catastrophic 😂

Am I crazy, but I don’t hear a difference between that piano and a regular piano

Size DOES matter!

Cool af arrangement.

It makes my small 77 key upright look like a small kid's keyboard.
