Knight Moves

This analogy or concept is based on how the Knight moves on a chess board.

It moves in an 'L' shape.

This L shape will be superimposed on to the 3 NOTES PER STRING SCALE SHAPE to determine the Major Scale chords for a given key.

Knights Move in an L Shape

On a chess board the knight travels:

  • 1 square, then rotates 90 degrees and moves a further 2 squares
  • 2 squares, then rotates 90 degrees and moves a further 1 square

3 NOTES PER STRING SCALE SHAPE

You need to familiarise yourself with position 1 from the 3 NOTES PER STRING SHAPES.

MAJOR SCALE CHORD FORMULA

The Major Scale has

  • 3 Major Chords
  • 3 minor chords
  • 1 diminished*

The MAJOR SCALE CHORD FORMULA is

  • m, m M, M, m, dim

*I am not interested in finding the diminished chord for this example as it is a bit of a niche chord (but pretty cool once you get in to it).

Once you have this KNIGHT MOVES concept down it will not take much for you to add that chord yourself.

Major Chords L Shape 

So in the C Major Scale, the Major chords are:

C, F, G.

  • Plot them out on to the "position 1" Scale shape
  • Within the first 6 notes of the scale
  • The L shape is formed :)

You can see that can't you?

If not look again, and look again. It is in there!

So if you know where your root note is i.e. C, then you can easily plot out the L shape to work out the Major chords.

Minor Chords L Shape 

So in the C Major Scale, the Minor chords are:

Dm, Em, Am.

  • Plot them out on to the "position 1" Scale shape
  • Within the first 6 notes of the scale
  • The L shape is formed :)

Again, you can see that can't you?

And again, if not, look again, and look again. For it definitely is in there!

So if you know where your root note is i.e. C, then you can easily plot out the L shape to work out the minor chords.

CONCLUSION

You can use this method to work out the chords for a scale.

  1. Decide on a root note.
  2. Plot out the Major Chords
  3. Plot out the minor Chords

It might be tricky at first, but once you have followed the process a few times it will start sinking in.

You can also use this method to work out what key a song might be in.

Plot out the minor chords for a given song.

Do they fall in that shape?

Say you had Am and Dm:

  1. Find the note A on the 6th string
  2. See if the 2nd note in the minor L shape contains a D.
  3. If not, see if the 3rd note in the L shape contains a D.
  4. If yes, then maybe you ave found the key.

Repeat the process with A as the 2nd note in the L Shape.

Do you end with an alternative key to use?

What about starting with the A as the 3rd note in the L shape.

Do you another alternative key to use?

TEST YOURSELF

So look at the songs listed at the bottom of MAJOR SCALE CHORD FORMULA SEQUENCES.

Map them out using the above procedure.

Change the key by moving the l shapes somewhere else on the fretboard.

Look at some other songs, what key are they in?

Check out your own songs, what key are they in?
