Current Guidelines for Aerosol Generating Performing Arts Activities

UPDATED November 30, 2021

Singing and playing wind instruments generates large amounts of aerosols and thus poses a higher risk of spreading COVID-19. Wearing a specialized mask when conducting these activities, as well as placing filtering bell covers on wind instruments, significantly reduces this risk.

The following guidelines are currently in effect for all curricular and co-curricular aerosol generating performing arts activities. They will be periodically reassessed based on recommendations from the University’s Pubic Health Implementation Team (PHIT).


There are no restrictions at this time; however, bell covers are recommended. As possible, maintain at least 8 feet of physical distance between the performers and others.



  • ASTM Level 3 or NATS-TMF Vocal Performance Masks* must be worn during all indoor singing activities, including routine rehearsals and classroom instruction.

Playing Wind Instruments:

  • ASTM Level 3 masks* with a slit opening must be worn and tightly fitted instrument bell covers fashioned out of ASTM level 3 mask material or made of MERV-13 or higher filter material must be used during routine rehearsals and classroom instruction.
  • Absorptive drip pads must be used by all individuals playing wind instruments indoors.

*Other commercially available options will be reviewed by EHS on a case-by-case basis.

Performances and Technical/Final Rehearsals:

  • For performance and technical/final rehearsals, the measures outlined above are recommended, but not required IF all unmasked performers submit three COVID-19 test during the week(s) of the performance and technical/final rehearsals. 
  • Maintain at least 8 feet between the performers and the audience.
  • As much as possible, performers should wear face coverings when not on stage.
  • Offstage areas must be appropriately spaced to avoid crowding.
  • Notify the audience, preferably ahead of time, that the performers may not be wearing masks.
  • Follow the Guidance for Conferences and Events.
  • For undergraduate student performances, performances must be attended by professional staff (appointed by the Office of the Dean of Undergraduate Students) to ensure compliance with mask wearing.
