Peter - there may be others who have interest in reading this info, so I'll respond on the forum.

I actually use an open D major tuning that is based upon a Nashville tuning; ie. the bottom four strings are an octave higher then the standard tuning. This creates an odd octave break between the 3rd and the 2nd string. It also creates a very pretty combination of high notes on the botton, with drone strings on top. There is a more detailed article about this tuning here, but I am now doing this with a full sized guitar too.

Anyway - this tuning adds to beauty of this haunting melody. I do use a slight variation of the melodies linked in the DT ... I will make a tape and send it to you, if you provide me with your mailing addr via PM.

To play the song, I finger pick and brush playing the melody a bit while I sing ... I use a chord that looks like the standard E7 and slide it up the neck to make the run from the root to the 4 chord, then use a minor based chord (with drones) and the 5 chrod. I could actually do a chart for this pretty easily. Then I'll post it. It should be done today. I'll be back with a link!
