I read this 10 page PDF ... which seems very good
now the question
If my face is totally relaxed my lips protude a little. So if I put my mp on that position my buzz will occur a little more inside ... we are talking a tad. The good is I have more cushion between my mp and teeth. The bad the inside of the lip could sneak in and give that horrible duck sound. The good there is more lip to curl in when getting up to the upper register and I don't seem to need to curl it very much at all. The bad ... it's easier to pinch the note. The good (well maybe good) instead of feeling like I have to push the mp in I feel like I am just bring the lips closer together (sort of clamping)
I think the reason I have "buzzed" or curled a little is because the tone seems more crisp.
I am asking because if this is wrong I could really screw my chops up.
