Well, I just had nice practice on my new rotary horn. We have a 'gig' concert for the parents on Thursday this week. Today is Monday, and we have a rehearsal on a Wednesday. Which leaves me tomorrow the last day to ask our band director if I could use my rotary horn. My teachers doesn't recommend it but I just went through our repertoire in today's practice and I sounded pretty good. My mother thinks it's better than my old Yamaha sound. I think it's more brighter, fatter and projects better. Should I use my rotary for the gig concert or just leave it?
