“Fourth chords” are chords built as a “stack of fourths,” rather than as a “stack of thirds.”An example of a “stack of fourths” would be: D, G, C, and F, where D is the lowest pitch, and the rest make up a series of fourths above that.
The greatest thing about these stacks is that any given stack can be superimposed above multiple roots, to create a variety of voicings for various chord types.
Using the stack mentioned above as an example:
A “Dmin7” chord using the stack D, G, C, and F, results in a nice open-sounding voicing, with an added 11th (the “G” note is the 11th).
D, G, C and F also sounds great over a B-flat root, creating a “Bb69” sound! That is, a B-flat major chord, with an added 6th and 9th. (G is the 6th, and C is the 9th).
And so on…my video here explains this in depth. (Check back soon for Part Two, with more insights on this.)

DESCRIPTION OF THIS VIDEO:
Piano and Music Theory – FOURTHS and FIFTHS – “Perfect and Not-so-perfect.” Essential knowledge for building chords without rote memorization, and for understanding chord progressions, plus understanding general music theory.
In order to understand tutorials on piano playing, it is essential that you know some basic terminology from the world of music theory. So here’s an important video on “major and minor thirds.”
If you aren’t clear about major and minor thirds, you might want to watch this. Afterward, you can read the rest of this article, using your newfound vocabulary!
Chords are often understood and learned as a series of “stacked thirds.” For example, a major seventh chord can be seen as the following stack:
Major third, Minor third, Major third.
Let’s look at the CMaj7 (C Major Seventh) chord as an example of stacking thirds to build a major seventh chord from any root. The notes of the CM7 chord are C, E, G, and B. Starting from the root C, we can stack thirds to create the chord. First we pile on the E, which is a major third above C. Then we put a G on top of the E. The musical distance (interval) from E to G is a minor third. Finally, we top off the stack with a B, which is a major third above the G. We now have a really tasty sandwich!
OK so here’s the video with some tips on finding major and minor thirds on your keyboard, starting from any piano key.

Essential information. And simple!
You can’t build scales or chords without knowing these two intervals.
Bottom line: The language of intervals is essential to learning all your scales and chords without resorting to the nearly-impossible task of rote memorization!
Today we have two video lessons, either of which is a good introduction to a pretty simple notion, which I sometimes like to call the “melody machine.” With this, I’m not suggesting some big new original conception. On the contrary, the concept I’m calling the melody machine is about as old as music itself.
If that nickname sounds a little gimmicky, it’s really not meant to be. I actually do call this device a “melody machine,” in my own thinking, part of an ongoing process of internalizing my favorite composition devices. Also, it’s fun to say, just like saying “Lollapalooza” or “Isn’t she pleasant?”
In a nutshell, this lesson shows you certain ways of using an underlying chord progression as a “thought generator” for creating melodic material.
