Okay, so my marching band is playing 'Welcome to the Jungle' this year for marching band. We usually have two weeks of practice in August and then a day or two after that practice ends, we have our first parade. Except my mom is making me go on a family vacation for two weeks, which would mean I'd miss all the practices. I got the sheet music early and have been practicing, but all the videos of other marching bands I find have other parts added on. The tempo is weird, the notes are confusing and the speed is questionable. I've been trying for a week. What should I do?!
