It's not absurdity. I stand by your son's school - the science is sound. Welcome to my wheelhouse.
Following multiple studies and a large-scale study performed in multiple phases, it has been determined that participating in performing arts such as band, choir, and orchestra are safe so long as specific guidelines are followed.
- Musicians must be at least six feet apart, with the exception being that there be nine feet of space in front of trombone players
- Musicians can rehearse in a facility for no more than an hour, with at least an hour afterward to allow aerosol dispersal
- Masks with holes for mouthpieces are acceptable for rehearsals, but a regular mask should be used for the remainder of the school day.
This is the information the colleges, universities, and most school systems are operating under.
Please reconsider depriving your child of this opportunity because you don't understand the science. Most students pulled from a performing ensemble never return.
