The overwhelming quality of horn material is hardness. The second quality is consistency of the material. For example there is a recent discovery that the highly valued Stradivarius violins were made from wood infested with a certain virus resulting from a climatic challenge. The effect of the virus was to eliminate hard spots in the wood creating a much more consistent surface for sound amplification. Right now deliberate use of such a virus is under study for violin making.
Obviously in working metals making certain that the metal is the same thickness and hardness throughout the horn has been almost a black magic or accidental happening in the past. Brass, being easy to machine, has been more likely to have some sort of consistency in production than materials that are more difficult to work with. This probably explains the use of immersion to near absolute zero in attempts to improve horns. The results of deep cold are most likely proof that the over all hardness of the material has been normalized.
I made no remarks as to braces and how they effect sound and do not want to confuse the issues.
There are blind studies that point to the fact that experts can not normally tell when materials in horns' bells are changed. Although artisans in the industry may wish things were a certain way science is not yielding the same answers.
I do not know where you get this misinformation. It is still the same BS when you repost it after a month. I would appreciate you letting me know who spreads such lies. People that I mentioned to you before like Renold Schilke proved and published exactly the opposite. Your blind studies with no reference to who, when or where must have been by deaf people. They may have been experts, but from the Consumers Union, not a musicians union!
I am not interested in this type of BS. Divulge your source. I have been studying this for 40 years. It would be hard to believe that this "escaped me" where exactly the opposite is easily available for all that care to look.
The theory of the wood virus in the Stradivarius was disproved long ago. Repeating the original false hypothesis does not make it more true, it just prolongs a lie.
Whenever I feel blue, I start breathing again.
As a matter of fact you could easily set up a blind test yourself with any trumpet made with changeable bells. Simply have a player in another room who can not be seen by any listener play with different bells and have your trumpet playing friends write down which bell was in use.
The world has seen this before. Wine testing has been almost debunked to the point of being a total joke when the most famous wine testers could not tell premium, classic wines from low priced, super market junk.
The point being that industries often have "experts" that simply are anything but knowledgeable. And even when instruments are used to inspect diamonds almost all of us have seen leading diamond dealers totally fooled by imitations. The truth can be quite illusive.
How does one blow the statue of liberty? I don't know but if you get it right she'll hit a high note for you!
I've blown it with many females. I even got hate mail from one date! But these days how do we know if the statue is really female. We can't even decide if Olympic runners are actually females these days.
I guess it is like the copper issue. A few years back the word gold was deliberately misused to indicate gold color rather than precious metal. Using that logic I suppose if you build a tin trumpet and spray it with copper colored lacquer than it must be OK to call it a copper trumpet.
