How To Play Guitar: 7th chords (NG12)

What's up future rock stars!!!
In today's lesson we are going to take a look at a bit more advanced chords, don't worry they are just as easy to play as the average major and minor chord. We are going to take a look at the 7^th chords, more precisely the major 7^th, minor 7^th and dominant 7^th chords.

This is the first type of tetrad chords that we are going to discuss, this means that they differ from the normal triad because they contain a fourth note.

Major 7^th chords

Let's take a look at the major 7^th chords first. You start off with a simple major triad, but you add a fourth note called a major 7^th (which is the 7^th note of that chords major scale, hence it's name).
The formula is: 1 3 5 7

Here are a few common shapes of this chord:

Emaj7: E G# B D#

Amaj7: A C# E G#

Dmaj7: D F# A C#

Gmaj7: G B D F#

Cmaj7: C E G B

Minor 7^th chords

The minor 7^th chord consists of the basic minor triad, but with an added
flat 7^th note.
The formula is: 1 b3 5 b7

Here are a few common shapes:

Em7: E G B D 

Am7: A C E G

Dm7: D F A C

Dominant 7^th chords

The third type that we are going to discuss today is the dominant 7^th chord, just like the major 7^th it starts with a major triad, but this one also contains
a flat 7^th note, whereas the major 7^th contains a major 7^th note.

Here are a few common shapes:

E7: E G# B D

A7: A C# E G

D7: D F# A C

G7: G B D F

C7: C E G Bb

note: most of these shapes can be moved around on the fretboard by turning them into barre chords, especially the E7, A7, Em7, Am7 and Cmaj7 are very easy to move around.
