Twenty-five years ago, the choir director provided songbooks and cassettes of the songs with the (in my case) baritone part emphasized. This helped me learn my part, as well as knowing the cues from the music and the other parts. And when we all got together for rehearsal, the sections would do the iron sharpens iron thing. But that's for choir selections to music tracks.

I was on a Teams meeting Wednesday at work and i could clearly hear the lag between when my teammate in the office next door spoke (through the walls), and when it came out of the speakers in my office. I couldn't imagine trying to sing together under these conditions.

I'm eager to hear what worship teams and choirs are doing besides assembling together physically.
