Check out the 2021 Fiddlerman “White Christmas” Group Project.
This was a short open instrumentation project for both singers and instrumentalists, a Renaissance madrigal where instrumentalists could play any of five parts on any instrument. I recorded the tenor line on viola.
If you have a Discord account and are interested in playing in a virtual orchestra, this may be a group worth looking into. I'm happy to send Discord server invitations to anyone interested. Although most of this group's projects are for advanced players, I understand the organizers have committed to running easier projects suitable for beginner or lower-intermediate players on a regular basis, and this was one of those.
