In our never ending quest for scientifically proof of what goes on in our trumpet playing world, we find yet another bit of information to confuse and delight our readers. Here is a video showing what actually happens in the cup of a trumpet mouthpiece as it is being played. For those with weak stomachs, please be advised that what you are about to see might be too graphic for the casual viewer. For the rest of us, it looks exactly as we thought it would. Enjoy and remember to keep buzzing, no matter what it looks like!
