POP AND JAZZ CHORD PROGRESSIONS #2

PREREQUISITE: Knowledge of the Scale-Tone Seventh Chords and the major scales.

In the last post, POP AND JAZZ CHORD PROGRESSION #1, we discussed how certain chords types tend to gravitate to others. I borrowed from (and took a liberty here and there :-\ ) Randy Halberstadt’s ‘Cosmos’ metaphor for theory discussion.

We focused in on just one of the twelve planetary systems within our harmonic galaxy with the sun being the center —the major (I) chord in the key of ‘C’. We learned that each sun has planets, (green) that surround and are pulled/gravitate toward it—these are the ‘Scale-Tone 7th Chords’—with the (V) planet (G7) having the strongest gravitational pull. Let’s zoom out and take a look at a larger picture; the pop & jazz harmonic galaxy which contains twelve solar systems; representing the twelve key centers. Below is a look at that galaxy. Here's a PDF DOWNLOAD of it for a larger look.

Without getting to scientific, technical, or philosophical, mostly because I can’t :-/ —keep this thought in mind. There is a motion, rhythm and vibration at every point in the entire universe. And what makes music pleasurable are those mechanisms that we hear and feel.

THE CYCLE OF FIFTHS

Looking below, we see that our harmonic galaxy moves counter-clockwise from sun to sun in perfect 5th intervals—what we call the Cycle of 5ths.

It is the natural order of all things musical.

This is your foundation… your everything for learning chord progression/movement, how they pull/gravitate to one another. This chart shows how key centers/solar systems move toward each other.

But, as you will see very soon over the next posts, each key center has its own cycle of 5ths. This is where you begin to put to use how chords move within the key of a song. And I will demonstrate how that will work with many familiar tunes.

Here’s what you need to know, and do, to get the cycle burned into the brain.

Even solar systems/key centers gravitate to one another. If you just have to know WHY it moves in 5ths, you can do a google search for the ‘overtone series’ for an explanation. This is your foundation, your everything for learning and using chord progressions/movement, and how they pull/gravitate to one another. Here’s and exercise for moving around the cycle of 5th galaxy.

BACK TO THE TWO MOST IMPORTANT INTERVALS

We said the two most important scale-tones in any chord are the 3rd & 7th? Even though we only discussed them pertaining to the (V) chord in the last post, which created the tri-tone interval, it does not mean that every 3rd & 7th tone of every chord is a tri-tone. Yet they are still the primary tones for all... chord recognition.

Now there may be sharpie or two out there that will tell me that there ARE chords other than the (V) chord that contain a tri-tone—and you’d be right. But for my purpose right now, I’m only talking about the most important one (the dominant 7th)—with the strongest pull home.

Why I segregate the (V) chord from others will become an ah-ha moment when I talk about chord substitution. OK.... on to the exercise. Let’s move from key center to key center, sun to sun, using only 3rds & 7ths (Are ya still with me? I know, this is a longy)

In the previous post you downloaded and practiced the (V) to (I) exercise. Right? :-) Well, here for the purpose of learning the 3rd and 7th scale-tones on (V) dominant 7th chords only, we’re going to take the (V) planet of every sun, (key center), and move it around the cycle of 5ths using the 3rd and 7ths tones in the right hand and the root/bass note in the left. Download the large PDF here before you go blind.
For any techies out there, some of the spellings are not enharmonically correct. It’s for simplicity sake. And for those that don’t know what I’m talking about... fa get a bout it. Just do the exercise.

Tri-Tone (V Chord/Dom7th) Practice

Through All The Major Key Centers

Here’s the galaxy representation of the above exercise. Check out the green planets. Stop squinting, you’re gonna hurt those eyes. Get the large PDF here.

Ok... one more exercise. We’re going to cycle around just the key centers (the suns) using the same format. Take a look below and also get the large PDF here.

Ok.... I think you’ve had enough. Good job. I hope that this is making some sense to you. I suspect I might be overdoing it a bit. Maybe I’m entertaining myself at the same time learning about all this graphic stuff? Can’t go back now... “straight ahead”, as one of my favorite music teachers used to say.

In the next post, I’ll be covering one of the moon’s that pull toward the planets. This will cycle us back to the first post on the subject. Then, we will have a complete understanding and working modal for the most important chord progression in pop & jazz harmony.... the (II) (V) (I) progression. And....

There will be many, many examples of how all this is used in tunes. I’ll be showing and recording a ton of sound files along with PDF’s so you could follow along. Thanks for listening!
