7 or 7th Chords

by Pete · 0 comments

7th Chords also known as dominant 7th chords are based on your standard major chords. Much like your standard major chords, it contains the first, third and fifth notes of the major scale, however a 7th chord contains an additional note. The 7th note of the minor scale.

There are three 7th chord shapes that I use.

The first and one of the easier shapes to remember is the D7 chord shape. The root of a chords is the first not of a chord. In this case it is a “D” for the D7, and for this chord shape, it is found on the third string (C string) remember this and it will help you figure out each chord up and down the fretboard.

The next shape is a G7 chord shape. Pictured below. Here, we have the root of “G” found on the 4th string (G string – try not to laugh at that). Here it’s open, so it’s a little easier to play.

If you move it up a couple frets, you will get an “A7” chord. Notice the “A” played on the 4th string?

The last chord shape is the “B7” shape, another easy chord to play. The root of this chord is found on the 1st string( the A string)

Move it back a couple frets and you get an easy chord to play. The A7 chord.

Play it against the previous A7 Chord shape and you will see they are harmonically the same.

Here’s a simple 7 shape bluesey cord progression you can play.
