Chord
structure
A chord is a combination of notes in a scale. Here we
discuss major chords. Let’s look at the chord C major. C major
consists only of notes in the C major scale or key. The notes that
make up a major chord are always the 1st, 3rd
and 5th note of that chords corresponding key. We know
the notes in C major are C, D, E, F, G, A, B and C again. The 1st
note is C of course…the 3rd note is E and the 5th
note is G. So in order to make a C major chord we need these three
notes. Let’s look at the C major scale starting from C on the 8th
fret (also referred to as the 8th position).
FIGURE 17

Notice where all the C’s, E’s and G’s are at. If you
take all the other notes out, it looks like this in figure 18 below.
FIGURE 18

This would be the pattern of a C major chord in
the 8th position (the Ionian or first mode of C major).
Now this is as basic as a chord gets. Let’s say you wanted to play a
C major 7 chord. This means you want to add a 7th note
from the C major scale. If we just said C7…this would be a C major
chord with a 7th note from the C minor scale…which
happens to fall just one fret lower than a 7th note from
the major version of C. If we said C minor 7…we would play a C minor
chord with a 7th note from the minor version of C. So you
see that C maj 7, C7 and C min 7 are three different chords. Now you
are probably wondering how to make a C minor chord...unless you
already know of course. Look at the 3rd note of the C
major scale…which is E of course. (Note figure 18 has only one E
note). In order to make a chord minor, you need to play the 1st,
3rd and 5th notes of the minor version of that
notes key…which in the key of C minor would be C, Eb and G. The C
and the G are the same 1st and 3rd notes you’d
play in a C maj…the only difference is the 2nd note, E,
is flat. All the notes in C minor go as follows…C, D, Eb, F, G, A
and Bb. So all you do to make any major chord a minor chord is
flatten the third note…in this case E to Eb. So C minor looks like
this in figure 19…
FIGURE 19

Figure 20 shows you how to play these chords in terms of
what fingers to use and what frets to play.
FIGURE 20

If these chords are difficult, you may need to practice
making them for a while. Of course there are plenty of open string
chords you can play in the first three or four frets that are easier
to play if you are a beginner, but remember that it’s also nice to
understand how chords are made in different voicing. The voicing of
a chord is a reference to the order in which the notes in a chord
are played and how many of each of a chords notes are being played
in the chord. For example, if you look at figure 18 again, you’ll
notice that the C Maj chord diagrammed shows you notes played in the
order C-G-C-E-G-C from the low E string to the high E string and
you’ll see that it consists of 3 C notes, 2 G notes and 1 E note.
These combinations can vary in many ways. You could play a C Maj
chord with any number of each of its notes in any order as long as
you only used C’s, G’s and E’s.
In figure 20, of course we are making C chords on the 8th
fret which is a C note on your low E string. That low pitched C note
is the root note of that chord. So in other words, you are using
that C note as the foundation of that chord. There’s another way to
make a C major chord using that same C note. There is also a way to
make 2 more basic C major chords using the C notes on the second
lowest bass string…the A string. These are the 4 basic ways of
playing a C major chord shown in figure 21. Of course there are many
other variations on making a C major chord…these are just to show
you the structure.
FIGURE 21

Figure 22 is similar to figure 21 but it also displays
the names of the notes that are being played on each string just
left of each chord so that you can see how many of each note and in
what order they’re being played. These are what you would call the
“voicing” or the way in which the chord is voiced.
FIGURE 22

All 4 chords in the diagram are C major of course, the
only differences are the number and order of the notes. Now you’ve
seen the four basic chord shapes lets look at the fret board with
just the C major chord notes…C, E and G.
FIGURE 23

Looking at figure 23 you can see all the C major chord
notes. You can make a C major chord using any combination of the C,
E and G notes in figure 23. Practice looking for and making
different versions of C major throughout the fret board. Remember,
of course, that you can move this whole pattern up or down to
whatever position you want…so that you can play in different keys. C
is on the 8th fret as you know, try moving the whole
pattern down just one fret to B on the 7th fret. Also…now
that you know how to derive a C major chord in virtually any
different voicing possible on the fret board, you can simply take
any C major chord that you find and move it up or down according to
the twelve basic notes and that will be the chord you will be
playing. Remember that if you are playing a chord with open strings,
you will also have to move those open notes up too…of course you
can’t move them down, because open is the lowest note on each
string. So for example, when you are playing any C major chord,
simply move each string up one fret…and you have C#, two frets up
and you have D…one fret down from C and you have B and so on. So now
that you know that you can find any major chord someone throws at
you just by moving up and down in position…and if you just count the
four basic chord voicings we’ve discussed in figure 22, you can make
every major chord at least in those four voicings not to mention all
the other possibilities of making a major chord that you derive from
figure 23. Remember where the four basic voicings sit on the fret
board in relation to each other and how some notes from each of them
will tie into the notes of the others. Remember also that a chord
only needs just one of each note in the chord to be considered a
full chord. A “chord” with only 2 notes in it is simply a pair and a
chord with only 3 notes in it is called a triad.
Now of course the C major uses the 1st, 3rd
and 5th notes of the C major scale. Let’s look at the
notes of the key of C again in figure 24.
FIGURE 24

If we start this key of C sequence from C…we have the Ionian
mode…and if we start from D, we will be playing Dorian mode. If you
recall that the mode only refers to which tone of the key (in this
case C Major) that you will use as your root note. Using C as our
root note…we make our root chord, C major, using the 1st,
3rd and 5th note of C major Ionian mode…which
is C, E and G as we know it. Let’s look at C major Dorian…which
starts from D in figure 25.
FIGURE 25

Of course the intervals move around a little. Now the D
note is the root of the scale. Still C major…just starting from D.
Notice that in the Ionian diagram in figure 24…the 1st
note is a 2 whole step interval from the 3rd note and the
3rd note is a 1 ½ step interval from the 5th
note. Now that we start from D…the first note, D is only a 1 ½
step interval from the 3rd note, F is now a 2 step
interval from the 5th note which is A. So in terms of
intervals (spacing between tones)…the 3rd note is
flattened in Dorian mode. You learned earlier that in order to make
a major chord into a minor…you simply flatten the 3rd
note. In other words if you were to look at the D major scale, it
would consist of the notes D, E, F#, G, A, B, C#...the 1st
note would then be D, the 3rd note would be F# and the 5th
note would be A. That’s D, F# and A to make a D major chord…so if we
wanted to play a D minor chord…we would flatten the 3rd
note…F# to just simply an F…leaving D, F and A which are the 1st,
3rd and 5th note of the C major key in Dorian
mode (starting from D…the second note of the key of C). So in order
to play your root chord of C major Dorian, which would be D, you
would have to make it a D minor for it to consists of just notes
that are in the key of C major in this case D, F and A. Each of the
seven modes is going to have its corresponding note as its root. You
can start the C scale from each note in C major to see how the
intervals move around if you like…otherwise just remember that the 1st,
4th and 5th chord is always major and the 2nd,
3rd and 6th chord are always minor. The 7th
chord is what’s called a minor 7b5. So in the key of C minor…it goes
as follows: C Maj, D min, E min, F Maj, G Maj, A min, B min 7b5.
Let’s look at the root chords of each mode as we move up
the fret board from C major in the 8th position. Figure
26 shows just the notes from the key of C.
FIGURE 26

In figure 27 below, we mark the notes C, E and G that we
use in the first of the four basic voicings.
FIGURE 27

The dotted frets make up the C major chord. Move each
dotted note up one note in the scale and you will be playing the
notes D, F and A…the same notes that make a D minor. The D minor is
shown in figure 28
Figure 28

If you continue moving each note up one note in the key
of C, you’ll come up with the sequence C Maj, D min, E min, F Maj, G
Maj, A min, B min b5. I, IV and V are major and II, III and VI are
minor…VII is a minor b5.
Let’s look at chords with the root note C. In figure 29
there are a few different types of C chords…some major and some
minor.
FIGURE 29

You manipulate any chord by adding and taking out
certain notes. To make a C major you have a C, E and a G hence 1st
– 3rd – 5th, so if we want a C major 7 we will
add the 7th note of the scale which is B…so we have C, E,
G and B. The C7 chord is still the C major notes, only instead of
adding a 7th note of the C major scale, you would add the
7th notes of C minor which is Bb…so a C7 consists of 1st
– 3rd – 5th – flat 7th. Of course
we know already that C minor is simply a flattened 3rd,
so that would be C, Eb and G. Finally, C minor 7 is simply a C minor
with an added 7th from the key of C minor. I hope that
from here you will be able to better understand how most if not all
chords are made up. You may not understand everything here in one
sitting, so practice and give yourself a fair chance to learn it.
Keep in mind that all of this applies to each key relatively.
