So, I have been playing viola in orchestra for many years, my High School Orchestra. I'm in Philharmonic, which is the second highest orchestra, and recently I told my orchestra teacher I want to switch to bass, b/c I really like bass, the sound, and I've played a little bit of Electric bass, and I love its role in the orchestra as well. So basically, and I most likely can't get a double bass before Monday, my orchestra teacher is going to give me a bass on Monday, which I can only use in class, and I'm wondering, is there any way I can get ready for it? Would having some experience with viola help me play bass perhaps? And will my orchestra teacher probably give me a cheat sheet for playing that day, because I'm going to hopefully start lessons this week, so very soon?
