Hey all - I have a new student playing about a month who can't seem to control his facial muscles "embouchure" . I swear he seems to have no muscle tone what so ever. He does have good pitch and rhythm and gets a sound. But his cheeks and his lips puff out with the pressure of the air. I thought that the muscles would strengthen over the next few weeks but not much progress is going on. I have tried having him tighten all the muscles of the face and make a tight expression then try to buzz on the moutpiece. This however does not work - the cheeks seem to have no strength whatsoever. I am ready to call his folks and encourage percussion. What would you do if you were me??? I appreciate any advice!! Thanks!!
