8.  UNDERSTANDING FORMULAS CONTINUED…

    CHORDS HAVE FORMULAS ALSO

Now for some other Chords

Major 7 type chord

All Major 7th Chords have the formula - 1 - 3 - 5 - 7

This means that any Major 7th Chord is made up of the 1st  - 3rd - 5th  and 7th notes of it’s Major Scale

Example 1.  Let us look at a C Major 7th Chord

                                   I     II   III   IV   V  VI VII   I

The C Major Scale is   C - D - E - F - G - A - B - C

The C Maj 7 Chord is  C         E        G         B      

So add the 7th note B

So you see the notes and formula of the

C Major 7th Chord are

Formula   1     3     5    7

Notes       C    E    G    B

I ALWAYS RELATE ALL FORMULAS TO THE MAJOR SCALE

NOTE

The C Major 7 Chord shown on Guitar uses combinations of the  1st - 3rd -  5th  and 7th  notes of the            

C Major Scale

Dominant 7 type chord (7th)

All 7th Chords have the formula - 1 - 3 - 5 - b7

This means that any 7th Chord (Known as Dominant 7th) is made up of the 1st  - 3rd - 5th  and b7th notes of it’s Major Scale

Example 2.  Let us look at a C 7 Chord

                                   I     II   III   IV   V  VI VII   I

The C Major Scale is   C - D - E - F - G - A - B - C

The C 7 Chord        is  C         E        G        Bb      

So add the b7th  note Bb

So you see the notes and formula of the

C 7 Chord are

Formula   1     3     5    b7

Notes       C    E    G    Bb


Notice the difference between a

Major 7 chord and             Formula   1     3     5    7

7th (Dominant 7th chord)   Formula   1     3     5    b7

The C 7th  Chord shown on Guitar uses combinations of the  1st - 3rd -  5th  and b7th  notes of the            

C Major Scale
