They also plan to sing for the doctors, nurses and staff at Grady Hospital.
The tunes will be played on public address systems at the hospital and the senior living center, said opera spokesperson Laura Lucas.
The opera, which has had to postpone two productions, including "Madame Butterfly," in the 2019-2020 season due to the coronavirus outbreak, has been looking for ways to assist in the fight against COVID-19.
Atlanta Opera is offering singing telegrams.
The opera’s costume shop, along with costume shops at the Alliance Theatre and the Atlanta Ballet, are all busy fashioning mask-covers for the N95 face masks, as well as hospital gowns, to be used at health care facilities.
“We are continuously amazed at the outpouring of kindness for our staff,” Lindsay Caulfield of Grady Health System told the opera, expressing appreciation for the gesture.
