I have PhD tutorials in a studio at my university, they’re deemed too risky for the foreseeable future, so they’ll continue to be via Zoom or Skype. That’s just two people, the studios are probably about the same size as a small rehearsal studio. We don’t sit close together anyway, but we’d still be in the same enclosed space for a prolonged period; usually an hour and a half. Just sat listening to my work and talking. There’s none of the physical exertion associated with a band playing, people standing up, moving about, singers singing, drummers drumming, sax players saxing etc. It’s madness in my opinion to want to play just yet.
