The U-Trainer for brass players is a helpful training tool to strengthen the embouchure muscles. Due to the ergonomic shape of the U-trainer, the mouth ring muscles (musculus orbicu laris oris) can be specifically trained. The resistance of the U-trainer can be optimally adjusted by different O-rings. In this way, the attachment muscles can be built up slowly and gently.

The U-Trainer Point is a helpful tool to centre the airflow of the brass player. The U-Trainer Point coordinates the chin, cheek and mouth ring muscles in such a way that the air flows into the mouthpiece in a centred manner, especially on high notes. This makes the high position on the instrument safer in the long run.
