Nice going Neil :0) Played fer ever and never did figure that out before, usualy don't look at the fretboard but now I am doing that again. Just had a thought there must be some relation between the tuning of the strings and the different positions? I guess what you are saying is the notes off the littlest string MY FIRST - begin again on fret 5 of the second littlest string MY SECOND, and then on the fourth of the next and so on. Hmmmm.

I used go through em like this, D maj off the Nut, then off fret 5 -3 finger thumb over back of neck- then off I think fret 10 -looks like an F chord-.

In D there are a bunch of Modal chords as well all over the place - wish Art or Rick would Post here. I dont know where to begin on this one, there are there believe me - fiddle around and have fun.
