After a student has learned how to make a sound on their new brass instrument, and make it consistently, their next focus is on improving that sound. Since sound starts with the mouthpiece, your first upgrade should logically be the mouthpiece. But when and how do you find the right one? Use these tips to understand the process and help you student take their fist steps to expanding their sound and skills.

Can it be this simple?  Find a "high note mouthpiece" or the "endurance" mouthpiece, put it in the instrument and you'll have better range/endurance?
