Harmonized G Major Scale

Harmonized G Major Scale


G Major Scale notes:


When you spread the notes of a G Major scale all over the fretboard (right), you get a visual representation of the Key of G. That’s sure a lot of dots! What do they actually mean?  Let’s simplify them to get a better understanding of how a key works.





Chords come from scales. To the left is the same fretboard grid but with the standard G chord forms highlighted in red.

This is better. But what about the notes that are left out of the chords? To find out, let’s separate and look at the first three open strings.







By eliminating the 4th and 5th strings, we can simplify the concept of how the key of G functions. Taking the first three open strings separately, we get the following:

By counting down and across each string, we can construct chords. The first three connections are shown here:

Combining the fretboards back together reveals the following three-note “diatonic” chords:

These chords harmonize the notes of the G scale down the length of the third string. There are three different forms:

1.) Three barre chords starting with the unfretted strings on top and on the 5th and 7th frets. It repeats with the barre G at the 12th fret.

2.) Three “pyramid” shapes ending at the 2nd, 4th and 9th frets.

3.) And finally, a partial D7 form which occurs one time near the 11th fret.
