I thought this was an interesting article with a really good explanation of how the mechanics of singing can cause a greater distribution of aerosols, potentially spreading COVID-19. The article is geared toward choirs but could apply to bands as well. Is Singing in a Choir Safe During COVID-19? A Voice Expert Explains the Risk - FOCUS - A health blog from Mass. Eye and Ear
I've seen the same information from other sources. I've also seen some real spitters behind a mic! This, combined with the close quarters among patrons at a bar or concert, make a musical performance one of the riskiest activities for COVID transmission, unfortunately.
That's a good article. I sing in a local choir similar to the one mentioned in the article (about 75 miles from them). Our director has been tracking the research and discussions about this. We almost became That Choir. We had a rehearsal scheduled for March 9 (the day before theirs),but fortunately canceled it. One of our choir members had contracted it, but was asymptomatic, so he didn't know he had it yet. If we had rehearsed, I would have been sitting right next to him for the entire rehearsal. For now, we're doing online rehearsing and virtual choir videos.
Wow! Thank goodness rehearsal was canceled. That's the really scary part of all of this - someone not knowing they could be contagious because they are asymptomatic or before symptoms appear. We're also doing virtual videos for church.
