Chord Construction - 3 Note Chords - Part 3

For this first example we are going to take an A major arpeggio and convert it to an Am.

Converting A to Am

Converting A to Am is easy enough. An A chord is A(1), C#(3), and E(5). Just lower the C#(3) on the 3rd and 1st strings down a half step to C(b3).

 

A

|---|---|-C#|---| -1st string
|---|---|---|-A-|
|-C#|---|---|-E-|
|---|-A-|---|---| -4th string
      |
      5th fret

A = 1, C# = 3, E = 5


Am

|---|---|-C-|---|---| -1st string
|---|---|---|---|-A-|
|-C-|---|---|---|-E-|
|---|---|-A-|---|---| -4th string
          |
         5th fret

A = 1, C = b3, E = 5

Sure, this Am arpeggio shape is a little bit of a stretch. But you may find a use for it at certain times. If you take that C note on the 3rd string and move it to the 4th string, you will find one of the most basic minor arpeggio shapes.

Am

|---|-C-|---|---|---| -1st string
|---|---|---|-A-|---|
|---|---|---|-E-|---|
|---|-A-|---|---|-C-| -4th string
      |
      5th fret

A = 1, C = b3, E = 5

Here is another basic major arpeggio shape.

A

|-A-|---|---|---| -1st string
|-E-|---|---|---|
|---|---|-C#|---|
|---|---|---|-A-| -4th string
              |
             5th fret

A = 1, C# = 3, E = 5

To convert this to a minor arpeggio just lower the C#(3) on the 3rd string down a half step to C(b3).

Am

|-A-|---|---|---| -1st string
|-E-|---|---|---|
|---|-C-|---|---|
|---|---|---|-A-| -4th string
              |
             5th fret

A = 1, C = b3, E = 5
