Before this class, you should play before band. Either at home or get to school early. It will take only 10 to 15 minutes to be ready. You can mpc buzz for 5 minutes, easy slurs in an easy register. After that I have an easy exercse that you can do for 5 mintes on the horn. If you would like,I can send it to you. Contact me via e mail. A few minutes of lip flapping first is great. It's how I start my day.
