Somewhere Over the Rainbow

So, I've made up my mind - I'm going to audition for the community musical, The Wizard of Oz. In preparation, I had my drum corps horn instructor create some sheet music for me, and I input the solo part into Garage Band (because I'm too impatient to wait for him to give me the recording..) I've chosen Somewhere Over the Rainbow, since it's encouraged to use music from the show. I have it on repeat on my ipod and am hoping that by osmosis I will burn the pitches into my head. I am also working on where to breathe. Auditions are the 24th. Wish me luck!
