Let’s clarify the tuning used before we start. I’ve gone for classic open D (from low to high): D A D F# A D. This stacks up like an E major chord in regular tuning but dropped down a tone.
Using open D as a starting point obviously means the goalposts have moved regarding fretting hand fingering and chord shapes, but what is lost in one sense is certainly made up for in opportunities for chords and melodies that would be virtually impossible in regular tuning. It’s also great for bottleneck and can be heard on many old blues recordings.
