Hello, I’m looking for advice on what to purchase. I have a cheap 20 key anglo concertina, which I play from time to time, but I’ve played string instruments for a long time. For some time now, I’ve wanted a concertina with chromatics and to accompany singing. What are some recommendations for a first English concertina? I looked online at a 30 key baritone English concertina (“Jack”) from Concertina Connection. Would this be appropriate, given my situation? John
