Two important “news dumps”, if you will!
ACDA has finally released a set of recommendations and strategies for choral groups. You can view that here. Of importance to note are different scenarios for face to face, hybrid, and virtual instruction for a variety of teaching levels.
CBDNA held their virtual symposium a few weeks ago, and all of the videos for that event are now available for viewing. In addition to some great material presented by Dr. Greg Martin and Adam Gumble from WCU, there are a LOT of other presentations on a variety of topics that can be adapted for all levels.
