Basic Practical Theory 8

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

NOTE:.

Now you should understand the Beginners Basic Chord Book

Each of the chord diagrams shown, show how the chord is made and how it relates to the major scale.  Plus by using the Musical Educator Slide Rules you can find more advanced chords in different positions, and find any scale or mode in any key too
