After Pierre BenSusan came to our town this past summer I became curious about His guitar tuning which is Dadgad. After 40 years of slowly losing interest in regular guitar tuning music I have had a great rebirth with DADGAD. It brings more life out of the guitar and is wonderful for creating and improvising, since the open strings match any notes on the second, fouth, seventh , and ninth fret ( and most of the 5th fret).
The sound can become repetetive if one does not learn the cord positions   and becomes competent enough to know what he ( she) is trying to express before trying to so . It's fun during the first few months to play the scales with the open strings ,adding the bass, but as Bensusan's works show, its not just the tuning that is important . It is the talent level of the writer, the heart of the artist ,and of course the skill level.
Thanks to all for their inputs , I find it all immensely interesting.
