You can "venture to say" what you like, but what I do is one hundred percent untutored. I know all about rhythm, tempo and staying in tune because I've painstakingly taught myself those things. And only idiots call me "Stevie." I'll let you off this once but if you ever call me that again I'll call you Holy Joe for ever more. I have no idea how trained Walter or any other traditional musician is or was. What I do know is that traditional music is caught, not taught, and, as I implied, a highly-trained musician who then comes into traditional music had better shed an awful lot very quickly. That isn't to say that you can't achieve a deeper understanding of classical music via your scholarship. Of course you can. But even that can't be imposed on you via "training" unless you want to be a concert pianist or an orchestral player. You do it for yourself. As John Seymour said, there's many a miner who sings in a Welsh male voice choir who has a deeper understanding of Beethoven than many a professor of music.
