Hi. This is my first post, and a fairly basic question about embouchure.
I am a comeback player (sort of) because I played French Horn for many years to quite a good standard but gave it up about 30 years ago. I was a lip-pressure player, for sure, in those days, although my endurance was never much of a problem (as I recall).
Now I'm older and wiser (hopefully) I'm now making a big effort to play without pressure. My question is, when I'm playing, should I allow air into the space above the mouthpiece between my lips and teeth, or do I need to maintain a tension to keep the lips in contact with my top teeth and gums? As I relax I find my top lip wants to "balloon out" a little just above the mouthpiece, and I can still get the notes o.k. but I'm bothered whether I should work to avoid it, or if it's bad technique?
ps. Enjoying the forum. Thanks
