I talked with the older kids and we found common ground as best as possible. We kept certain things that I didn't care about but they did. We added certain things that were important, (like starting with the ability to actually read and perform as a concert ensemble in August). There were a handful of seniors that absolutely hated me and tried their best to make life hell. Most left on their own in December. A few were removed. Some stayed to try and be difficult but they learned that it was going to be my way, (honestly, the marching band culture was the worst part of it and after that season ended it actually got better because there wasn't a fight to have). I had strong admin support so we weathered it. We got better the first year but it was a fight. Year two there were still a few new seniors "longing for the old days" but again, we plowed through and got better. Year 3 was when I was the most comfortable and when we really started having success. I spent a lot of time showing them how they were improving and slowly they were seeing different was okay.
