What every musician should know about “chord stacking”…

So you want to play big, fancy chords! Who doesn’t?

And yesterday, I pointed you in the right direction.

We got introduced to polychords, which are essentially big chords made from two or more smaller ones.

So today, we’re going to take it a step further. Rather than stack “common” chords on top of each other, we’re going to see what happens when we venture outside the norm.

For example, if you stack a 5-major chord on top of its 1-major chord (like G major on top of C major), you’ll easily get a major ninth chord:

(C + E + G) + (G + B + D) = C major 9

*G is only played once.

Then, by simply changing one or the other to a minor chord, you’ll get a totally different chord:

C minor + G minor = C minor 9
(C + Eb + G) + (G + Bb + D) = C minor 9

(You can revisit yesterday‘s post to catch up if you haven’t)

So, this basic “5-chord over 1-chord” is what I’m calling “common,” for the purposes of this post. Master those and you can pretty much play any ninth chord. In fact, change your five chord to a seventh chord (i.e. – major 7, minor 7, or dominant 7) and that will give you all your 11th chords — even some fancy altered ones.

In fact, if you take a basic 1-major 7 chord (like C major 7) and start experimenting with chords off every tone of the chord, you will find matches that create bigger chords.

Don’t believe me?

Ok, the notes of the C major 7 chord are C+E+G+B. So basically, I’m telling you to play around with chords off “E”… chords off “G” (like we’ve done in prior examples)… and even chords off “B.”

If you take each one of the tones (not including “C”) and play random chords on them, you’ll come across things like this:

C + E minor = C major 7

C + E major = C augmented major 7

C + E diminished = C dominant 7

C + E + G major = C major 9

C + E + G minor = C dominant 9

C + E + G diminished = C dominant 7 (b9) (pronounced “C dominant seventh, flat nine”)

*This is a great 6-chord. Like if you’re in the key of Eb and you’re going from Eb major to C (which is the 6th degree), play this chord and it gives you a nice bluesy feel.

C + E + G + B diminished = C major 11

*You can also try “B major” and “B minor” like I did in the other examples but you’ll get some really altered chords. They are used, but rarely.

Heck, you can even experiment with chords outside of the scale.

Like Ab major over C major (you’ll get a cool altered chord that sounds really good on a 3-chord that progresses to a 4 or 6-chord. Like if you were in the key of Ab major and used this chord to go from C (the 3-chord) to either Db or F (the 4 and 6-chords, respectively).

The good news is that these combinations and possibilities are practically everywhere.

And I believe you should reserve a portion of your practice for what I call, “exploration.” This is where you take proven rules and ideas from this blog and experiment further.

For example, the rule learned in the last 2 posts is that you can stack smaller chords to create bigger sounding ones. So you take that rule and run with it! Explore and you never know what you’ll find!

Until next time —
