19 Aug 2010DADGAD Tuning
DADGAD (Sometimes called Open Sus4) is a really interesting alternate tuning for the guitar. It was made famous by the British folk gutiarist Davey Graham, who used it extensively. Jimmy Page is another figure who popularized the tuning by using it on the epic Led Zeppelin tune “Kashmir”.
I’ve been using this tuning a lot lately–and while it’s interesting one to improvise blindly in–sometimes it helps to know how to get certain chord types and scales. For that reason I’ve created this post as a reference for anyone who needs the same information.
To arrive at DADGAD tuning, simply tune the high and low E-strings down 1 step to D, and tune the B string down 1 step to A.

This is a nice page, but it would help if you had a key to let us know what they difference between the blue and black dots are in your graphics. I’ve tried several variations of open and fretting with mixed success. Since I’m a relative beginner this would help. A bit more clarity for the scales would help too. (I came to this page looking for “movable scales” for DADGAD tuning. Sorry if these concerns seem ignorant.

@Brett Blatchley:
Hey, don’t worry about it, and thanks for stopping by.
To clarify, the blue notes are root notes, and black notes are regular notes. The ‘x’ means not to play that string. So looking at the first shape for ‘major’ lets say we wanted to play an E Major chord. First notice that for this shape the root (blue) is on the 4th string from the highest (which is tuned to D). Now knowing that simply find which fret would be an E note in our DADGAD tuning–which turns out to be the second fret (when I get some time I’ll post a diagram of notes on the fretboard in DADGAD tuning). Anyway, knowing that… all you have to do is form this shape starting with the root note on the second fret of the D string, so the resulting chord would be: xx2122 — E Major.
It’s the same thing with the scales as well. Simply find the note on the low E string (which is now a D) that is the root of scale you want to play. So if you wanted to play A minor, you’d start now on the 7th fret. Simply play that ‘shape’, but starting on that fret and you’ve got that scale, which on the lowest string at least would look like this:
D-----------------------A-----------------------
G-----------------------
D-----------------------

D-7-9-10-12-14-15-17-19-
I hope this helps, if not please let me know if you have any additional questions.

Really helpful. I should get off my but and map these things myself though.
Thanks for the post.
