The Basic Music Theory You Need As A Jazz Beginner

Having the basics down in music theory is an incredibly powerful tool. If you are playing Jazz then interpreting chord symbols can be very difficult and if you have a solid basic overview of what notes are in there, you can find other ways to play the chord and add notes and fills to it, the things that make it a lot more fun to play!

That’s what I want to show you in this video because an overview like that is going to stop you from sounding like a Pat Metheny Clone, and instead of learning a single Jazz lick, you can figure out how it works and turn it into a recipe for 1000s of Jazz licks. There’s a chance you know a lot of this, but then you can use this as a checklist to see if you have it all under control!

The Most Important Scale For Jazz

The place to start is the scale that you need the most: The Major scale.

I assume you are already somewhat familiar with the but to keep it simple let’s use the C major scale:

The important thing to remember is that a major scale is constructed by a series of whole and half steps, and that recipe is:

On guitar you have a shortcut which is a physical solution where you are just moving a shape around,  that means that if you play a C major scale then you can turn that into an D major scale by just playing the same shape but start on the note D,

but that also means that you don’t really know what notes in there anymore, and when you play songs then it is very practical to know that the next chord is the IV chord in the key and that is THIS note in the scale, so here’s how you can start figuring out the notes in a scale.

I am going to show you this using D major as an example, but it works for any note can think of. It is just about using sharps and flats You need to remember or write down the row of intervals that make up the major scale:

For D major you can write out the notes from D to D . You can then go through the scale and make sure that the intervals fit and then correct that:

D to E is fine, but E to F is a half-step which should be a whole-step, so you turn the F into F#.

Now F# to G is a half-step so that is fine, G to A, and A to B are both whole steps

but B to C should be a whole-step as well

and again you turn the C into a C# to fix that and then you have D major

The next thing to do when you know what notes in the scale is to map that onto any scale position: just start on the root, play the scale, and say notes – in that way this is as much about connecting the things that you know on the neck, because that is where it is useful!

Dmajor:

That is the basic construction of the major scale, but what you need is to link this to chords because when you are playing a song then it looks like this:

The Strongest 3 Notes In The World

The Strongest Chord we have isn’t a Jazz chord which would be a chord with at least a 7th, The strongest chord only has 3 notes and it is, of course, the triad.

 

The basic construction of a triad is a stack of 3rds, so for C then

C major is 1 3 5 – C E G which is really just 1 3 and 5 out of the major scale:

 

C minor  would be 1 b3 5 C Eb G and the difference is the distance between the two first notes: C to E is a major 3rd

and C to Eb is a minor 3rd

Like this, you can also construct a diminished triad which is: 1 b3 b5 in C that would be C Eb Gb and you can create an augmented triad which is a major triad with an augmented 5th: C E G#

Those are the 4 basic triads, but you probably also want to know these 3:

Sus4 where the 3rd is replaced with the 4th:

Sus2 where the 3rd is replaced with the 2nd:

If you check then sus2 and sus4 are actually inversions of each other, so they are the same structure.

Another triad that is maybe less common in songs but very common in chord structures is major b5:

But right now, this is all just structures without any context, and while it is nice to know then the best way to know this is to place them in a scale.

The Strongest 3 Notes In The World, In The Scale

As I mentioned then chords are created by stacking 3rds, and actually that is easy to do in a scale so to construct the diatonic harmony and place the triads in a context . That tells you which triads go together.

Start with the C major scale:

and we can put 3rds on top using the notes in the scale to get first a row of diatonic 3rd intervals

and then these triads which is another useful row to remember, just like the intervals:

It is incredibly useful to know what triads go together, and as you will see later it is a huge help in finding more arpeggios you can use when improvising over a chord, which means more melodies that you can use in your solos

You can do this with any scale, and you should certainly know the triads of the major scale by heart, so this order:

It is also important to figure this out for Harmonic and Melodic minor which will give you examples of the other triads, you’ll see later.

Enough with the triads for now, let’s get to some Jazz chords!

The First Group of Beautiful 4-Note Jazz Chords!

In Jazz, we don’t work with triads as the basic chords so often, even though we still play triads in solos all the time.

The basic chord type is the 7th chord, but constructing the 7th chords is now super easy, barely an inconvienience: You just add another diatonic 3rd to the triads!

So these:

Become these:

Again the order of chord types is really useful to know, so for a major scale it is maj7, m7, m7, maj7, dom7th, m7, ø

And as you can see you there are 4 chord types in the scale:

The reason that I construct chords in scales is because that added context really tells you a lot about what is going on in the music:

If you take this lick:

As you can see that if over the over a G7 then you can use a Bø arpeggio which is the diatonic arpeggio from the 3rd of G7, so we are combining the knowledge of the chord with the diatonic harmony.

You can also see that the Em triad sounds great on Cmaj7, but that is just because an E minor triad, E G B, is a Cmaj7, C E G B without a C.

And the same thing applies to chords:

If you play II V I that sounds like this:

Here I am using an Fmaj7 chord, which is giving me the Dm7(9) sound:

and a Bø Chord for a G7(b9) before moving down to Cmaj7, so the diatonic chords become a part of how you learn things, and you cna use the same stuff for a lot of things, it is very efficient.

Of course, at some point you have done that so many times that you will just know what the notes of Dm7 is and that the arpeggio from the 3rd is Fmaj7, but being able to figure it out is a necessary step, and knowing it like this is, of course, a lot better than just having a diagram that you are moving around without knowing what is going on.

The Rest of The Beautiful 4-Note Jazz Chords!

As I said, there are more chord types than just the 4 I already covered.

To find some of those then let’s try to build chords in Harmonic minor, because that should give us some more. To keep it easy, A harmonic minor:

To get you more comfortable with the process then we can start with the triads

A B C D E F G# A

Then you have:

Am Bdim Caug Dm E F G#dim

And once you add a 7th to this then you get:

Notice that the G#dim has a diminished 7th from G# to F, that sometimes a bit confusing because it is the same interval as a 6th

And to immediately show you how useful this is, in the II V I in C I used the arpeggio from the 3rd of G7, and you do the same here and use a G#dim over an E7 because it is almost the same notes and they are from the same scale:

and, that is an great way to play an E7(b9) resolving to Am,

Working on this is something that can really speed up your learning process, because if you start practicing diatonic triads or arpeggios while also being aware of what triad or arpeggio you are playing then you

  • Have a better overview of the harmony and the scale
  • See the shapes you need for soloing on the fretboard
  • Figure out what is being played in Jazz solos so you can get that into your own playing.

All stuff that makes it easier to learn and play Jazz, but it probably isn’t going to be useful if you don’t learn any songs that you can use it on. Learning songs become a lot easier if you understand the harmony, and I talk about that in this video covering how I use Functional harmony but also how Barry Harris and Pat Martino have shortcuts that are opposite of each other, but it will all help you learn and remember songs. ! It doesn’t have to be difficult to learn songs. Check that out

If you start to figure this out for the different keys and practice diatonic arpeggios while also being aware of triad or arpeggio you are playing then you start to connect all of this and that will help you:

  • Know the scale and the diatonic harmony
  • See the shapes on the fretboard
  • Understand how the chords move

You can figure out what is being played in Jazz solos

And, all of these skills are important things that will speed up your learning process, but it probably isn’t  going to be very useful if you don’t learn songs and also learn to understand how the harmony works and that you can check out by watching this video which covers how I use functional harmony for that, but also how Barry Harris and Pat Martino think about chords and make things easier! Learning and remembering jazz songs doesn’t have to be difficult!
