Hey everyone. I have been told by two college professors that I play with too much of the lower lip and not enough of the top. So, I have to modify my embouchure to use more upper lip; I have to "roll the top lip into the mouthpiece." So, what can I do to accomplish this? I cant't stop playing because I have many performances coming up. One professor told me to try and use 1/32 of an inch more of my top lip every week and I really want to know how I can do this and what I can practice to help this. Would Schlossberg help? Thanks SO much for your help.
