@Tess_ogar It can vary depending on a number of factors. Open communication on the matter is key to working through it. I would say be spontaneous about it sometimes but make sure it's also high on the list of planned activities.
@DaDutchess5 I can relate to this. It's really an amazing on-going experience. The other day I got roped into playing at my kids' school concert with no rehearsal 🤭 I ended backing all of the vocal acts.
