This question was posed by a concerned community member, and the answer is unfortunately not a conclusive or straightforward one.
Research is currently underway around the world, which some of the below resources will describe, but is still in the developmental stages. We have included guidance from reputable singing organizations such as the American Choral Directors Association (ACDA) and the Barbershop Harmony Society (BHS). AdaSAFE is not taking a position of advisement for or against with these materials; it is providing materials to help community members make informed choices based on the research that has been done and what is known about the safety of singing during COVID-19 by the broader singing community.

American Choral Directors Association (ACDA) released guidance and a statement of support for choral singing and study during the COVID-19 pandemic on June 15. (Click here to download "The COVID-19 Response Committee Report.) The “COVID-19 Response Committee Report” was developed by a team of choral professionals from across the country, and with expertise and experience in choral education and conducting in a variety of choral settings including K-12 schools, colleges and universities, community choirs, and places of worship.
Monday, June 22, 2020: The webinar included ACDA President Lynne Gackle, ACDA Vice-President André Thomas, and the 13 Response Committee members. They summarized and discussed the report’s contents. Click here for the recording.
On June 4, ACDA’s Executive Committee announced the formation of a response committee to the COVID-19 pandemic. Its task was to create a document endeavoring to provide a strong, unequivocal statement of advocacy for choral music in our culture and choral musicians. Additionally, the document offers considerations and current parameters for ensembles, scenario planning with instructional and community-building models to guide our thinking, as well as resources that guide us in the direction of additional information in the near future and beyond. The ACDA COVID-19 Response Committee is representative of membership throughout our country and is representative of all regions of ACDA. Read full description and list of committee members here.
