Why is it that I can play my best when my lips feel moistured, thin and smooth, but I can't do as well when my lips feel thick and dry (not chapped). In other words I cannot play in the morning ( after breakfast), but I can play after a day of school, talking, eating etc. My lips aren't chapped or hurt, I just don't know why my lips are this way... Why do I get a double buzz after a little bit of Arban #4 scale patterns? As I play it I get a double buzz when I get to around a F (top of the staff). When I play note by note up the staff and come back down, my sound either gets very airy or the sound chokes off. Ex: F to G to A to B to High C back down to B to a airy A to a choked off G. As I do play these things I make sure I am not tense, or too tight, my lips just stop vibrating and it's downhill from there. I don't use lip balm or chapstick by the way. I've also feel like my chops are running out quick. Really weird. Any advice?
