For years I've been using what I always heard referred to as drop-D tuning -- i.e., standard tuning with the bass E lowered two frets. I always used it in the keys of A or D and it gives a wonderful, full bass line.

Today I was watching a video on slide guitar with Keith Wyatt and he was demonstrating what he called drop-D, but he lowered the treble E. I realize it is effectively the same tones, just in different register, but I had never heard of doing it that way.

Is this news to anybody else, or has my troglodyte existance just caught up with me?

cheers,
