Greg is the master and has it figured out – unfortunately I don’t. I really want to change to this way of playing but I’m having trouble getting off the ground with step one. I struggle and struggle with getting the ooooh formation to produce a tone. I get just air most of the time. Sometimes on the lead pipe I get a sound. When I move to the trumpet, if I do get a sound it is not good at all. I work with the lead pipe each day for a while and then move into regular playing with my regular setup. I don’t want to move ahead in the course too quickly if I can’t get this initial step correct. Any tips to getting over this hurdle? Just be patient and stick with it? It does feel way open and very loose compared to what I am used to.
