Get one and practice! There are lots of bands out there looking for you! I REALLY miss playing cello and I’m dying to get one but they cost a billion dollars and they are hard to come by. I’d settle for a viola if I could find one that’s not terribly expensive. I’m checking thrift stores and craigslist regularly. But I’d jump for joy and do all sorts of crazy happy dances if I could get my hands on a cello that’s in playing condition.
