I do have a large amount of experience and I have seen the profound difference that changing a mouthpiece can have.
I do not dispute at all that a player with monster chops can play anything from low register to the highest register with ease.
Unfortunately I am not one of these players. I therefore rely upon the mouthpiece to assist me in playing the notes I can reach in my range.
I fully accept the criticism that my chops are of low to medium strength.
On the other hand the meaning I seem to be gathering from your posts is that everyone has monster chops and mouthpiece changes wont help them at all. I would disagree with that if that is what you are saying.
You say that many in here could be hurt by my encouraging them to check out their mouthpiece choice.
It seems to me that they would be hurt more by forcing them to persevere with a bad mouthpiece and waste many years of their lives coping with bad equipment.
Do you know what trumpet the OP was playing on, do you know what mouthpiece the OP was using. Isnt it important to know that their equipment is good and functioning correctly before blaming the player.
Lets talk turkey. I have seen players using equipment so damaged that it was very difficult for them to play well.
It might take 20 years hard work to overcome equipment faults that are very severe. Or it might take just 2 minutes if they just swap the equipment for good equipment that works correctly.
I also seem to be seeing in your posts an assertion that all mouthpieces are fabulous, and no mouthpiece can affect a player badly.
If this is the case why do you not play on a cheap 3 dollar mouthpiece from India or from China.
Could it be that your monette mouthpiece plays more evenly through the ranges than the 3 dollar trashy item from AliExpress.
And if the monette plays more evenly through the ranges that must mean that other mouthpieces do not play evenly through the ranges.
And one last thing. Why are you so opposed to a player simply trying a different mouthpiece.
It costs nothing will give an instant answer. Then you know.
Or let us argue for weeks on whether or not we should pop a different mouthpiece in, and all we would lose is 15 seconds doing that.
You can lose weeks or months arguing about whether to try it, or you can lose 15 seconds trying it out.
If a player says a different mouthpiece cannot possibly improve their playing, my reaction is have you tried it or are you just talking.
And if they say oh no I would never under any circumstances try a different mouthpiece I would say ok no problem you do you.
Is it really blasphemy to say your mouthpiece might be holding you back.
I am willing to say that, and be condemned as an evil man for suggesting that some mouthpieces might be better than others.
When I recently passed an Olds Special to a friend who played on a 7c, I offered two 7c mouthpieces with it. An Olds 7c and a 7c by another manufacturer.
He tried both and found the Olds 7c played better. Are you saying it could not possibly have played better.
He was not a fabulous player with cast iron chops, and he found one of the mouthpieces to perform better than the other. Both were 7c and one suited him and his instrument better.
Is there something wrong with this.
I believe it is folly to claim that a mouthpiece change cannot affect playing. The entire mouthpiece industry is based upon the fact that a mouthpiece change can affect playing.
So what are we arguing about.
I say, find the best mouthpiece for your instrument, and your reaction is to say NO!
Can you make this make sense. I am all ears.
If it were me I would spend 15 seconds slamming a different mouthpiece in that I thought might improve things, and find out the truth there and then, and then move on. Job done.
But then I am a pragmatic guy and I just do stuff.
There is an approach to not getting things done called Paralysis through analysis.
Too many people spend months or years analysing things by research and it wastes their time.
They might spend months analysing everything to decide if they should try a different mouthpiece when all it takes is 15 seconds to try it.
No discussions or research or reports or investigation or polling the opinions of specialists or experts are needed. Just try it.
This is the core of the issue.
If a student cannot play as well as they would like, and the problem is the mouthpiece is wrong or bad. One approach would be to spend a couple of years on lessons in the belief that the equipment must be fine.
At the end of that couple of years they might play better or they might not.
Or
They change the equipment and if the equipment now functions better they have saved themselves 2 years.
That is 2 years they can now spend on improvement and not on coping with bad equipment.
Do we want to waste students time or solve their problems.
