This clever device from Gebr. Alexander in Mainz is an important tool which assists the player in retraining themselves to perform without the common vice of excessive mouthpiece pressure. The adjustable adapter fits between the mouthpiece and the leadpipe and allows air to escape as a warning when the player attempts to exceed the desired maximum pressure. A must for every teaching studio, and any student who fights the constant temptation to resort to mouthpiece pressure as an element in their playing.
