The "Brio" was created to train the muscles around the mouth and correct the embouchure in order to achieve a beautiful embouchure when playing brass instruments. It has a hole in the middle, allowing you to blow air through it, and can be used for diaphragmatic breathing training in addition to muscle training. Recommended for those who are struggling with embouchure stability or are just starting to play brass instruments. Used only a few times and is in excellent condition.
