Playing every day, but not all classes meet everyday and not all kids come on the the day their band class meets (it's a totally FUBAR schedule). We keep the kids 12 ft apart, mask on as much as possible when not playing, we disinfect every chair and stand used after every period, and don't share any materials. We've had at least one kid a week be prohibited from coming to school for two weeks. Sometimes, multiple kids in a class. Some kids have not been back since they were prohibited from coming. Most of the kids have told me they have tested positive for COVID-19, but there is no way to tell if they got it at school. Because of this, the district not only maintains no cases have happened on campus nor do they actually report any cases.
