Hello friends. This morning I received an email from a "famous" historical trumpet maker. Althoug I attended various trumpet making courses -which is the only activity of him currently- he wrote "please, don't tell you studied under me, you only attended to some of my trumpet making workshops". Well, as far as I know, that's the only chance to study with this man. I can't understand what the hell... I'm ashamed of the money I spent in this courses. In 2.004 -Rostock, Germany- I remember how I completed my trumpet in only one day and a half. Then I asked for the acids (were used in the Middle Ages) so they said: "no acids. Just sandpaper". Could you belive ??? All of us spent one week polishing our trumpets. When mounting the trumpets, we released that the tube of the bell bow was thinner than the bell bore (about 1 milimetre !!!), so tubes didn't fit. When a friend and I asked what happen, what to do, he said: "well, that's a good question. I'll think about". That was in 2004. Actually still waiting for the answer... So by now I'm proud to say I'm self-trained. I earned my Master in Trumpet Performence, as well as my Teaching Degree, my Phisycs-Acoustics prize in 1.998... I had worked for the Stomvi company in 1998, testing and designing new developments -but not in the workshop area-. I know about acoustics, I'm a good player... so the only thing I missed to start making trumpets was the skills I planed to learn from this two men (R.B & R. S.). Now they refuse to me. Great !!! I'm making historical trumpets since 2004, modern since 2007, and my customers are so happy. Well, I supose I'm self-trained. It means good things for me. Now, I teach trumpet making courses. But I'm always honest (I try, at least). All those who attend to them, are provided of REAL TOOLS, and I never let them down, for sure. Thanks to all. Supose I saved some bucks on a psiquiatryc... Best wishes !!!
