I love decay. Verymuch. That is what I tune first...

Speed of sound in granite is 5950 m/sec. Its speed in water is about 1/4 this, (1497 m/sec). Granite however is only 92% as fast in sound conveyance as aluminum, 46% as fast as beryllium for example. Some glass, most steels and irons, titanium ect.. exibit the same speed as granite so I am wondering what properties granite has that would make it stand out the choice here in comparison? Glass can be easily molded, steel can be forged, stamped or machined. Granite and most stones on the other hand get a slight impact or cut/saw in the wrong way and will crack.

Johnkie, I was listening to a system with liquid filled speaker cables just this weekend. They are amazing!

Mark, Johnkie, Emmery,

A smart person listens to factual logic, and we do have factual science from cymascope.com as well as other sources in the private sector.

I can't post the results here but you can see them on my Stonetone facebook page for now until my website goes online.

Besides the science and the credible folks who have already noted this as a revolutionary concept I am here to divulge some aspects of what is to break into your industry once a manufacturer gets a hold of this.

Our presentation is the 1st made public so far.

Relax and enjoy what is to come don't be ignorant to the concept because you have minimal knowledge of stone in general and or the attributes based on the mineral composition and it's comparison to wood.

Seems your attitudes are more like the mushroom which they feed on **** and grow in the dark. Time to come out of the dark ages and do your home work to know really what your talking about. Sure isn't gardening.

I think it may be mass and rigidity. A massive, rigid bridge should have lots of inertia, which is why the attack gets lost, and it might stay in motion longer than a bridge that is less massive. But I agree that the choice of material seems rather arbitrary. I also think that the change in attack is detrimental to the sound. After all, one plays a lot more short notes on a piano than long ones, so if the balance is between an interesting attack and a slower decay, I would put the emphasis on the attack.

Emmery,

Stone is natural, PERIOD. every other mineral you mention is tweaked by a process... The process that granite has endured man cannot explain. Even the science sector has theories but thats all they are. There is no process that granite endures other than being quarried which doesn't affect the natural occuring process in which it was created. The magic lies there and yet to be explained but sure as the scientists get further with this they will have some type of explanation that can be explained in leman terms.

Gee Robert, nothing like being full of yourself. But it's nice of you to take the time to let us know were about to enter into the "Stone age".

Like Mark Twain said, we will beat you with experience. Might be worth wasting some of your brain cells to 'temper' your approach; if you really want to sell this to the industry and the general public.

(just my 2 cents)

I've only been researching for 12 yrs. on this concept, so I do have allot to share but not until my patent issues. Dave B relax this is a good thing for all artists for ALL stringed instruments. i am a journeyman in the stone industry as well as a musician so by having both perspectives I've developed Stonetone.

Thank you.

Bdb is right on target.

As I've already said ....... I'll wait until respected piano manufacturers adopt new techniques and materials. Too many times have I hears of brilliant new ideas and concepts ... most of which simply vanish into obscurity.

I really don't see any need for rudeness Robert ..... you have your views and others are perfectly entitled to hold their own that may differ. From what I see so far, you are merely promoting yourself and name calling other technicians that have every right to doubt any amazing breakthroughs in piano technology.

Interesting. Reminds me of that glass soundboard we saw before

On these recordings, this approach sounds not balanced to me. Indeed the treble sings a lot. But the bass is almost totally lacking. Even the lower tenor is already lacking power IMHO.

Johnkie pay attention here !! remember this comment from your friend that you agreed with?
"downright gobbledygook" you call that an opinion? The truths I've shared are Fact not what mark calls "downright gobbledygook" now you see when folks get sarcastic the same can return so I ask "do you need a tissue"?

Wouter,

You tube really isn't the proper place to have a true judgement and has no comparison rather than in person but for now this is all we have at the moment.

I have a 1963 9' concert grand 2/3 way completed, once this is done by Christmas this should really tell us allot by doing a better quality grand than the crude story & clark.

It is always so, the new is very often viewed with the suspicion especialy when it comes to piano industry. I personaly have a great deal of respect for exploring and bringing new ideas. But, as a pianist I can say that the sound on the recording does not convince me at all, it is rather impoverishement of the sound than enrichment. Yes, there is better projection, initial attac seems to be better, but in the end I cannot see how this can be felt through the finger. I do not belive there is the dept under the fingers in which a pianist can explore various colors and types of sound. I think every pianist knows that feeling. Many of new pianos these days are a technology mastered to the last detail, with a lot of "improvements" that, viewed from the technical point of view should bring a lot, but in the end, when a pianist sits on the piano, the depht does not exist, the magic does not exist, the piano is simply grey in color. So," Stone tone" to me as a musician sounds from the beginning a little bit odd, we actually try to avoid a type of "stone tone"... But, the concept of the piano tone nowdays changed a lot, so, who knows...maybe it is a future... I dont know, maybe I am strange for that, but I think I can hear the wood in the piano tone and the way the tone travels through he whole piano, to me, wood gives the nobility in the tone... Of course everyone has his image in the head of the tone projection, something like singers, you could be amased what kind of pictures do they have in head when it comes to the descreibing of their way...

Very kind of you to offer a tissue, but no thank you, and sorry if you feel that I'm not paying attention. You no doubt are very passionate about your breakthrough, where as I am not. I have tuned and serviced too many fine quality pianos during my career to have need to worry unduly about issues of lacking sound quality and the need for any radical changes in designs. If something turns out to improve performance and quality of tone, great ... but it would tend to have to prove itself over time before being readily accepted.

You say your granite bridge changes the ADSR to ASDR and in so doing, requires more treble dampers to counter the additional sustain .... I wouldn't view that as an improvement at all ... more an evolution to a completely different instrument. Part of the very soul of a pianoforte is the essence of initial attack,and decay. Altering the relationship of sustain over and above the normal ratio between attack and decay is in effect, changing it more to properties more suited to that of an organ.

I like the sound of the claire da lune on that little grand. Not a very good recording, however, which is a shame. I think you've been a bit too quick to start promoting this - you're not able to show any decent evidence to support your claims, so you seem to be relying on a lot of conjecture, and attacking anyone who is sceptical.

Now you might be convinced of the healing powers of the Earth Frequency 528Hz. But I'd advise strongly against wrapping that up with your promotion of this product. To convince the industry you will have to convince the hardcore sceptics, and nothing turns off a sceptic like hearing how some arbitrary change of tuning can create magical results. This makes Kary Regragui's review practically worthless - all it convinces me of is that he has an unscientific mind.

I've also looked for your facebook page and have been unable to find it, as I was interested in the 'science' that you say Cymascope have done for you. But looking at Cymascope's website, it looks like they are just the producers of a pretty way to visualise sound, a new type of oscilloscope. And as I can't find the images or what have you that they've produced, then there's no way to know if this is going to be useful.

Please bear in mind that to call something 'science' you are making certain claims. You are claiming that you have conducted experiments that are as objective as possible to test your hypothesis that granite bridges are better. You have gathered evidence that support your hypothesis, from repeatable experiments. And although of course this is a commercial venture and so you have patents to protect, it should be possible for outsiders to verify your experimental data.

Until you can support your claims with some of the background science, none of us can verify what you are saying, so it is purely conjecture. No matter how much you say it is science, until the evidence is there, for all intents and purposes to everyone except you, it is not. It is mysterious and new, there are many claims made, but that is it.

I'm looking forward to hearing what Keith Akins has to say after he has seen the piano.

I, like many others have said, will reserve judgement until a real comparison can be made. The next retrofit you do, you should record the piano before it is done and after, using high quality recording equipment. And all other parts of the piano should stay the same. Then a direct comparison can be made, and your claims will be held up to proper scrutiny.

Even better - keep two pianos side by side, identical apart from the bridge (expensive I know!)

All the best to you though.

The thing that I notice most in this thread is that the the "pitch man" is insulting the very people he is trying to pitch to.

Not the most effective marketing technique.

Take care folks, I am done here and defiantly don't need your rhetoric.

You want science???? email ( John stuart reid) owner of www.cymascope.com and mention Stonetone® he will clarify that of all the pianos he has tested our our little prototype had by far the best looking partials he has ever seen.

Oh well. What do you think guys - six months to market? A year?

With that attitude I'm sure it won't take long...
