I did a new video on the Open D tuning. My original one has over 200,000 views. Crazy. This one is basically showing two shapes in Open D that will allow you to play most any song when broken down into it's basic harmony.
My internet sucks at home; I'll have to check that later. I have written a number of songs in Open D tuning in the past year or so. I now have two guitars at my gigs, one in standard and one in open D.
