I use them all the time, but I don't know what they're called.

They look like this:

D|-4---6
A|-5---7
E|-3---5
   G-? A-?


So for example, i've got G something and A something shown above. What are they called?

I'm thinking that the G is D/G because of the F#. And the A might be E/A because of the G#

Am I right?

You could call them D/G and E/A. They also contain the same notes as Gmaj7 and Amaj7 chords without the thirds.

I would just call them D/G and E/A, probably. I don't know what others would call them.

If you're going to play them, you're going to have to add a note each to imply what they are. If those are in root position(the root/1 is in bass), then you have the 1st, 5th, and 7th degrees for each, but the problem is that they don't have a 3rd which is needed to imply major or minor tonality.

If you were to play Gmaj7, you could play:
-
-
4
4
5
3

or

-
3
4
4
X
3

You could use those same forms with every note moved up 2 frets to make Amaj7.

Hm that's what I typically see as a maj7 voicing but of course it depends on context.
