can anybody explain to me what it means when a chord is a seventh? like G7 or D7?

Play a major scale.
For example, C Major
8-C (repeats the first note)
The 7th note is B. If the chord was C Major 7, you would add the 7th note (B) to the Major chord (which is 1-3-5 or C-E-G). So, C Major 7 is 1-3-5-7 or C-E-G-B.
However, you asked about a "7" chord, which isn't a 'major' chord. '7' chords are played with a flatted 7th note added. So, a 7th chord is 1-3-5-b7 (ie: C7 is C-E-G-Bb).
It's actually pretty easy. Take some theory lessons - it's the basis for all the music you will play.

Ya I think I got it now, thanks! I'm am taking guitar class at school but we haven't learned much theory so far. When should these type of chords be used? I appreciate the help

Yep, in blues you can use a flatted 7th pretty much whenever you want.
The Dead used them a lot more like traditional classical music, usually to give the chord a stronger function. A 7th chord with the flatted 7th wants to resolve down one string and two frets: A G7 wants to resolve to C, a C7 wants to resolve to F, an F7 wants to resolve to Bb, etc.

here's a good example to just listen for the differences. Play Black Peter......first NOT using the 7ths.
Code: Select all
A D A D
All of my friends come to see me last night I was layin in my bed and dying
Now try it with the 7ths.
