G'day,It's been interesting to read this thread. By coincidence, I had e-mail contact with someone in US who had the e-mail address beginning DADGBE~. After the main matter of discussion I asked if this was a guitar tuning he favoured and practiced ... Indeed yes ... small discussion of what I now note is the "drop D" tuning I see mentioned at times.
Although I decided to head in non-guitar directions some decades back ... I had, from basic musical pronciples seen the attraction and approach of this tuning - and immediately thought that there would be a vast gulf in perception and approach between its practionaers and those of "open (chord) tunings".
I am interested to see, so soon afterwards, confirmation of this theory and all its impications!
Regard(les)s,
