This morning I spent 15 minutes just buzzing on the leadpipe. Over and over, just the same pitch, maybe a little variance above and below. A few times the pitch dropped way down – an octave or so, I can’t remember. After maybe 10 minutes I started getting a quiver in my lips. I assume this is because I’m using muscles I don’t normally use when playing that they were getting a bit tired. Am I right thinking this? I’m also thinking how in the world I’m going to translate this into my regular setup… This makes me realize that I probably have been using a lip pinch/smile to achieve my upper register all these years. Ugh.
