While generally noodling around on a friend's guitar, I accidentally stumbled upon a rather awkward, yet somehow still warm, chord. It was D, A, and E an octave up. Now, I know that's two fifths, and it's also a fifth with a second plus an octave. Beyond that, I have no idea what it's called and I haven't really seen it get much use. Does anybody out there have any idea what it is?
