Guitar Lesson – Music Theory Part 8 – Scales and Modes

In one of the previous post, we looked at how you can use the major scale to create other scales by starting on a different note.  These other scales are also known as modes.  In that post, we started the pattern from the 6-note and created the minor scale:
          6  7  1  2  3  4  5  6  7  8
C major:        C  D  E  F  G  A  B  C
A minor:  A  B  C  D  E  F  G  A             
 
Now let’s take a look at what happens if we tried starting the pattern from the other notes.  Each scale or mode also has (Greek) name.  Remember, the root of each of the scales below is the 1st note.
C Ionian (major) :   C  D  E  F  G  A  B  C
D Dorian         :      D  E  F  G  A  B  C  D 
E Phrygian       :         E  F  G  A  B  C  D  E
F Lydian         :            F  G  A  B  C  D  E  F
G Mixolydian     :               G  A  B  C  D  E  F  G
A Aeolian (minor):                  A  B  C  D  E  F  G  A 
B Locrian        :                     B  C  D  E  F  A  B 
       
This gives us the basic idea of how to figure out the patterns of the other scales.  Let’s look at the different patterns side by side: (W= whole step, H = half step)

Ionian (major) :      W  W  H  W  W  W  H

Dorian         :      W  H  W  W  W  H  W
Phrygian       :      H  W  W  W  H  W
Lydian         :      W  W  W  H  H
Mixolydian     :      W  W  H  W
Aeolian (minor):      W  H  W
Locrian        :     

Now if we apply these patterns to the same root we can see the differences between the modes (which is really the important thing to remember):

                     1  2  3  4  5  6  7  8
C Ionian (major) :   C  D  E  F  G  A  B  C

C Dorian         :   C  D  Eb F  G  A  Bb C
C Phrygian       :   Db Eb F  G  Ab Bb C
C Lydian         :   C  D  F# G  A  C
C Mixolydian     :   C  D  F  G  A  Bb C
C Aeolian (minor):   C  D  Eb F  G  Ab Bb C
C Locrian        :   Db Eb Gb Ab Bb C

In some upcoming posts, we’ll start looking at what scale patterns might look like on the fretboard of the guitar.
