What chord is this?

Work on learning the fretboard - you'll be able to figure it out from the notes. It's E-E-B-D#-G#-E... that's Emaj7

It's E-E-B-D#-G#-E... that's Emaj7

But if you move it, still playing the open E strings, what happens then? That's got to change the chord, but not like a barre chord when all the notes are moved the same number of frets. It'd have to be a different chord at each position.

Now if you don't play the E strings, then it would always be a major 7 chord with the root note dictated by your position on the 5th string. At least that's what it would seem like to me.

Yes, this is correct.

If you're playing with the open E's, you just have to figure out what degree of the chord the E is, and that, along with knowing the spelling of each type of chord, will get you what you want to know. Of course, if you started treating the open strings as your root, that could turn your world upside down. :shock:

If you move it and keep the open Es, the chord name will depend on the position. You'll always have a major 7th on the center four strings... so it'll only be a major 7th chord if E is one of the notes on those strings - otherwise you'll have some extended or altered chord. You'll end up with four, since a major 7th chord has four notes: Cmaj7 at the 3rd position, Emaj7 at the 7th, Fmaj7 at the 8th, and Amaj7 at the 12th.

Some of the other voicings you'll get will be ok... Bmaj7/11 at the 2nd, Dmaj9 at the 5th, Gmaj7/13 at the 10th.

That leaves you with the altered ones that are out there: Bbmaj7#11 at the 1st, Dbmaj7#9 at the 4th, Ebmaj7b9 at the 6th, F#maj7#13 at the 9th (perhaps the ugliest of the lot) and G#maj7b13 at the 11th.
