Having just returned from another day of teaching, I have been noticing a couple of the beginner clarinets have the continual problem of blowing the cheeks out when playing. I seem to have sorted this with all but one, who after begin told last week to try not doing so, is still doing it. I know this is something that has to be corrected now, not later, but I can't think what else to suggest.
Has anyone experienced this a lot? Are there any good ways to stop this happening? I suggest looking in a mirror, stopping air going sideways, the obvious things.
