6. Students on campus should not participate in activities like those listed below, because of their potential for spreading the virus through respiratory droplets:
- Playing wind instruments
- Indoor sports
School gyms, weight rooms, and indoor workout facilities are to remain closed for purposes of athletic or fitness activities to both students and the community. Outdoor sports are allowable only if they can be conducted in accordance with Department of State Health Services guidance.
So like I said if TEA says "No playing wind instruments" that is what UIL has to follow. Considering the TEA language does not specify indoors or outdoors, just "on campus" this would mean no playing a wind instrument anywhere.
