I’ve been playing viola for a couple years now, off and on. Cut my teeth as it were preparing to play viola in a community level orchestra concert that included excerpts from Dvorak New World symphony (no pressure!).
I’m playing viola in a summer string orchestra again this summer where we’re playing Tchaikovsky string serenade and other (for me) challenging pieces. I just wish I could “get” a good vibrato. It’s different enough from low strings where I have 35+ years experience that I just can’t seem to do it from the inverse position!
