Buzzing

my lips buzzed after the 20ish minutes of practicing with just the mouthpiece of the trumpet. i was asked to practice making the siren sounds as a way to control not only airflow, but pitch as well. let me tell you that i'm not very good, so i gave up after 20 minutes. i am determined though, so you'll probably hear more about it this week, especially since i don't have my saxophone right now. awww..
