The Jazz Chord Rules Every Pro Knows But Nobody Teaches

Did you ever look at a jazz chart and think,

“I have NO idea how to play this?”

I’ve been there too, but once I discovered the 3 simple rules that every pro knows but most guitarists never learn, the chords instantly made sense.

So in this video, I’m going to show you the 3 rules I’ve used to help 100s of my students play through any jazz standard, so you can have fun making music without feeling stuck on complicated chord symbols.

Most jazz beginners miss one relationship that explains 80% of the chords—once you see it, jazz standards stop feeling random. And that’s Rule #1.

Rule #1 – The Key

Look at this song.

If you’ve ever opened a real book chart and thought, “What are all these chords?”, here’s the good news.

Most of these chords belong to one key. Here, the key is C major.

And once you know the key, the chart stops being random—you understand most of what is going on.

Knowing the key is like watching a series you already know. You recognize the main characters.

And you know their roles—which one feels like home, which ones move away, and which one creates tension that wants to resolve.

For example, in C major, Cmaj7 feels like home… and G7 is the one that really wants to go back home.

Listen to this:

Now let me show you how to learn the whole cast in C major with one simple shell-voicing exercise.

Learn the Chords in the Key

Now, if you want that “home and tension” feeling to be automatic, you need to know the main cast of the key on your guitar.

So here’s the simplest exercise.

We’re in C major. Let me show you the 7 basic “in-key” chords you get from the C major scale, using shell voicings.

Shell voicings are the perfect place to start because they are easy to grab and nail the sound plus that you can expand them into fuller jazz chords later.

Here are the chords for C major:

Just focus on this: play it in time. Then you will get used to the order and the sound of the chords.

I was playing them slowly with a chord on each beat, but you can make it two beats per chord as well.

The goal isn’t just memorizing a list.

The goal is: when you see something like Dm7 to G7 on a chart, you instantly think:

“That’s in C major—and I know how to play it.”

In a second, I’ll show you the same chord family on a second string set—so when these chords show up in a song, you can grab them without jumping all over the neck.

Completing The Chords

Now that you can play the chord family, here’s the next step—so you can grab these chords the way they actually show up in songs.

All the chords in the previous exercise had the root on the 5th string,

but you also need the ones where the root is on the 6th string to make it easy to play jazz standards without jumping around the neck.

Here’s how to practice it:

Start on the lowest chord shape you can find on that string set, and move up the neck.

You’re not always going to start on Cmaj7—you start wherever the guitar gives you the first available shape. I’ll explain why that is important after the example.

And here’s why this matters: it gives you an actual map of the key on the fretboard.

So when a chart hits you with the next chord, you’re not hunting or counting from the root—you just see it.

This is how you stop feeling like the neck is a maze.

Easy To Play The Song

Check out how easy it is to play Fly Me To The Moon:

Let’s start with this Am7 on the 5th string, now the closest Dm7 is this, and G7 is very close. Resolve to Cmaj7, again, Fmaj7 is close. Now we move to Bø, down to E7 and then land on the Am7.

Now, E7 isn’t in the exercise for C major chords. It’s an extra dominant that pulls you to Am7.

Don’t worry about the theory yet—I’ll show you exactly how to spot these later in the video.

Notice what just happened—I wasn’t thinking chord-by-chord.

I was grouping things, using the key.

And that’s also what Rule #2 is about: stop memorizing chord-by-chord, and start learning progressions in chunks.

Rule #2 – How A Pro Thinks About Chords

Try to remember this sequence:

G — V — 1 — T — 4 — R

Did you get it? It feels random.

Now look again:

GV1T4R

Suddenly it’s familiar: “GUITAR.”

That’s chunking—grouping symbols into an idea you already know.

And that’s exactly how pros think about chord progressions.

Because if you try to memorize a song chord-by-chord, it’s like spelling every word out loud, letter-by-letter.

Pros just read words.

The #1 “word” in jazz: II V I

So what’s the most important word to learn first?

The II V I

Once you can spot II V I’s, tons of songs stop being random letters and start being “oh, that pattern again.”

Let’s look at Solar.

Even if you’ve never played this song, watch what happens when we stop reading chords one-by-one and start reading chunks.

Right here is a II V I to F.

Then the same idea again—a II V I to Eb.

Next is a II V I to Db.

And finally we get a minor II V I that takes us back to Cm: Dø G7 Cm6

So instead of thinking, “That’s 12 different chords I have to memorize,” you’re thinking:

“Oh—this song is basically a few II V I progressions put together”

That’s why chunking works: you’re not memorizing symbols… you’re recognizing the language.

Other Chunks

Once you can spot II V I’s, you’ll start noticing other common chunks too.

Don’t try to learn a giant list right away—instead, recognize these when they show up in the songs you play, because you need to really know them and it should not just be theory

Chunk #1: Turnaround

Sounds like this:

Chunk #2: Minor II V I (that you already saw) Dø G7 Cm6

And also IV IVm which has many beautiful variations: Fmaj7 Fm6 Cmaj7

Chunk #3: IV to IVm

The key is to recognize them in songs and treat them like one move, not 3 or 4 separate chords.

That’s how this stops being “theory” and starts being music—and it’s why playing jazz standards gets easier and easier the more songs you know.

So now you can see the chunks.

But remember in Fly Me To The Moon we hit a chord that didn’t fit our C major chord family?

Rule #3 explains exactly what that is—and why it shows up everywhere in jazz.

Rule #3 – The “Other” Dominants

Remember that moment in Fly Me To The Moon where one chord didn’t fit our C major chord family?

Those two chords—E7 and A7—weren’t in the C major chord family we practiced earlier.

But they sound completely natural, and here’s why:

They’re secondary dominants.

What’s a Secondary Dominant?

A secondary dominant is just a dominant chord that points to a chord other than the I chord.

In other words: it’s an extra “V chord” that helps you get to another chord in the key—like Am7 or Dm7 in Fly Me To The Moon.

So even though that dominant chord isn’t in our C major chord family, it isn’t random—it’s pushing the song forward.

Look at Fly Me To The Moon:

E7 is the V of Am7 → it strongly pulls to Am7

A7 is the V of Dm7 → it strongly pulls to Dm7

That’s why they don’t feel random. They feel like an arrow.

How to spot them fast on a chart

Here’s the shortcut: When you see a dominant chord that looks “out of key,” ask:

“What chord is this trying to go to?”

Most of the time, it resolves down a 5th (or up a 4th).

Just like the two examples in this song:

E7 → Am7

A7 → Dm7

Why this matters?

This is why secondary dominants are everywhere in jazz: they create forward motion—tension → resolution—without the song actually changing key.

You’re still in C major… you’re just using an “extra dominant” to make the next chord feel inevitable.

The Secondary II V

Sometimes jazz makes the pull even stronger by adding the II chord in front of the dominant.

So instead of just V → target, you get II → V → target.

And the “II chord” changes depending on what you’re resolving to:

if the target chord is major, it’s a major II–V

if the target chord is minor, it’s a minor II–V

In Fly Me To The Moon, the target is Am7, so we get the minor version: Bø → E7 → Am7.

But if the target was the IV chord, Fmaj7 you would get a major II V:

And that’s Rule #3: spot the secondary dominants, and you’ll stop getting surprised by “out of key” dominants—because you’ll know where they’re going, and how they work.
