What can I do so I don't need much warm up time? In my class in high school my teacher usually gives us a minute to play on our own before a test then we play in front of the class. Usually for me I don't feel warmed up for as soon 10-15 minutes, but that's with my own lip slurs. I gradually get higher lip slurs so it becomes easier to play a high C, I can't just get my horn out and play a high C like it seems like everyone else can. I really am looking for a solution to this, as it is killing my test scores and chair placement.
