Tip: THE "5"

In a previous post we tinkered with a chord’s 9. This time we take a look at a major chord’s 5.

Five, Nine? What are these? Quick refresher. Let’s see the notes of a chord and the numbers we refer to them with:

C, E, G
One, Three, Five

Take a look at the bigger picture: ONE of the scales that includes the C major chord:


If you count to the D, you’ll see it is nine. But back to the fifth of the chord. Here’s what happens when you increase the fifth of a C major chord by one half step, or one fret:


That’s a C Major Augmented or a C+5. What can you do with such a creature? How about put it in place of a regular C major chord:


You won’t find a C+5 in any major scale — that’s one of the reasons it might sound kind of surprising to you. You will find it in these two minor scales: harmonic and melodic minor. And because it shares two notes with the minor chord whose root is a third below the root of the plus 5 chord, you can experiment with substituting the plus 5 for that minor chord. Here’s an example:


Have fun exploring the Major Augmented chord. Thanks for reading.
