I've got an interesting gig coming up, that is very different for me. I'm playing in the pit band for a musical. My old high school is doing a rock opera and my former choir director (yes I was literally a choir boy in high school, among other things) emailed me and asked me if I'd play guitar for it. I said sure and she sent me the score and some rehearsal tracks. I've been learning the songs and there's a little bit of everything, ranging from folk type stuff to ragtime to straight up rock. We have our first group rehearsal next week and while I've had a lot of fun learning the songs I'm admittedly a little nervous. I've never played in anything that might be referred to as an "orchestra," in the sense that we will have a conductor, etc. All of my guitar experience has been in rock bands in some way or another, or playing solo. I want to do a good job, not only for myself but also for the kids that are performing in the musical. Any advice?
