This will probably get everyone riled, from here to the North and South Poles.
I started playing playing clawhammer about 3-4 weeks ago. I have been playing 3 finger style since 1980. I wish I had started playing clawhammer long ago b/c I am loving it. I know my way around the fingerboard OK though I'm no professional. I dedicated a week to bum-ditty, then saw a youtube video, someone used the phrase, BOOM cha-ca-la-ca-la-ca, which seemed good. I practiced that and the bum-ditty some more. Before long, I was playing some songs, not fast, nor especially great, a little clumsy I imagine.
I use the thumb and index finger. So last night, I got the idea to see if I could strike the strings properly, with ring finger and little finger planted on the head, and use the middle finger to strike upwards. It's probably against the law or something, but it was not difficult. I practiced an hour or so last night, and again this morning. Of course it's slow going at first, but that's just a matter of developing muscle memory. Going slow, I did not find it difficult to mimick 3 finger rolls used with 3 finger style picking. It was kind of fun. Like it says in Ecclesiastes, there's nothing new under the sun.
I was wondering if anyone else had tried this approach.
I once heard, "if you copy what others have done, all you can hope to be, is the worst of the best, or the best of the worst". I experiment with just about everything I do. Sometimes success, sometimes not, but even failures have positives.
