Didn’t understand it?

Ok, let’s take an example. Consider the C major chord. Any major chord is formed by combining the root note, the third note and the fifth note. So the dominant 7th chord of C major (denoted as C7) will be a combination of the root note, the third note, the fifth note and the flatted 7th note (see below).

The C major scale is:
C D E F G A B
1 – 3 – 5 – b7

So, C7 = C E G Bb

Now look at the C7 chord below. Focus on the third fret of the third string. That is the Bb note. That is the note added to the regular C major chord.

Let’s take another example.

Consider the G7 chord. First we will write the scale of the G major chord. Then find all the relevant notes.

The G major scale is:
G A B C D E F#
1 – 3 – 5 – b7

So, G7 = G B D F

Now look at the G7 chord below. The first fret on the first string is the F note which is added to the regular G chord.

Isn’t it easy now?! Figure out the rest of the chords below yourself.
