Hidden Diamonds

Here's a pattern that will reveal a lot about the nature of the fret board. In Fretography, the yellow field in the diagram below is called the Mixolydian Super Zone. Notice that its lowest note is on the 5th scale degree. This is a very useful pattern in that it spans a wide range in the center of the key system. In the key of C major, it runs from the 3rd to the 7th fret.

In the notation above, you'll see that there is a unison D on the 3rd and 2nd string. When playing this pattern it's a good idea to play both D's because their positions are an essential part of the symmetry. Knowing where both of these positions are will really help you find your way around. Remember that D is the only note in the key which is found in such a symmetrical relationship with itself.

The diagrams below show the Mixolydian Super Zone (yellow) and the Hidden Diamonds (blue). Each  diamond has a D (green star). The upper diagram shows the pattern as scale degrees, the lower shows note names. You can use the scale degrees to understand how this pattern works in any key by shifting it to different fret positions.

The two diamond shaped blocks comprise four triads. One diamond contains the notes D, B, F and A — the other; D, F B and G. These notes produce the following chords: D minor 1st inversion, G major 2nd inversion, and both a 1st and 2nd inversion of B diminished. The following notation shows these four chords ...

The symmetry of this group of chords is very strong. Study the diamonds in the diagram and notice the positions of the following pairs of notes; A—G, F—B, D—D. These pairings correspond with the overall symmetry of the Diatonic system. Notice the role of D in all four chords. Also notice the shifting inner tones — B, A, G, F which descend through the tritone.

The notation below shows the same ida with the two last chords shifted down an octave to emphasize the descending inner tones (blue) ...

To clarify the symmetry, the diagram below shows the pattern broken into its upper and lower string groupings ...

In this closeup of the upper four strings, pay special attention to the relationships of the following pairs of notes; I — III, IV — VII, V — VI and II — II. These notes will always fall in rotationally opposite positions across the string group, from the center outward.

Now let's look at the same notes in the lower string group, an octave down ...

And a closeup of the lower forms. Notice that II is at the very center of the array and in the upper left and lower right corner. Again, look for the I — III, IV — VII, V — VI and II — II note relationships ...

The next of the "diamonds" are actually triangles spanning the upper strings of the Void position which comprises the 10th through 12th frets in the key of C. In any major key, the tonic will be on the 4th string within the Void Zone.

In the diagram below you see all three basic forms with the Void in the center and the upper & lower strings separated ...

Here's notation for a riff in the key of G major, using the lower shapes shown above and the void position triangles ...

Finally, here's a diagram of all the "diamonds" within the lower four strings ...

Look at the connected forms in the center of the lower four strings. Notice that the combination forms root triads II - IV - VI and V - VII - II, or D minor and G major in the key of C. This cluster highlights tritone which is common to both diamonds.

All together these hidden diamonds contain five of the seven notes of a major key; II, IV, V, VI and VII. Only the Tonic and the 3rd are left alone.
