Have you found the perfect trumpet mouthpiece? Does it help you through difficult passages and make the upper and lower register sound exactly like you want them to? Does it support you when you are tired? Me neither. Surely there is magic in a trumpet mouthpiece right? It’s how we connect to our horn, how we make the music. Yes, our lips form an embouchure (om bah sure) which the mouthpiece turns the buzz into a sound that gets changed into a note in the trumpet. But is that all they do?
