Many residents are music aficionados. Covid-19 has been tough on social gatherings, and that has put a damper on the opportunities available to enjoy live music. Consider bringing a musician in your community to play live music over the intercom for a short duration, or to a small group of residents inside a room with lots of open space. Residents who can play a musical instrument could even serve as the musician, playing live for their fellow neighbours to liven the mood!
