Economical Guitar Triads - An Easy Way to Dominate the Neck
Triads are the most basic chords you can play on guitar, consisting of
just three notes. Therefore, we only need three strings to play them.
Now, I like to make your time learning guitar as productive as
possible. So in this
lesson I'll not only show you the most economical way to play these
triads, but I'll also show you how to dominate the neck, in any key,
using
a simple method known as scale harmonization.
First, take a look at the video below for a clear introduction to this
powerful method...
Guitar Triads in Theory
There are four triad types that form the basis of harmony in music:
Major triads, which consist of a root (1),
major 3rd (3)
interval, and perfect 5th (5)
interval. 1 3 5.
Minor triads - root (1),
minor 3rd (b3)
and perfect 5th (5).
1 b3 5.
Diminished triads - root (1),
minor 3rd (b3)
and diminished
5th (b5). 1
b3 b5.
Augmented triads - root (1),
major 3rd (3)
and augmented
5th (#5). 1
3 #5.
Note: In the video, we didn't use augmented triads, because they
don't exist in the particular scale we were harmonizing. That doesn't
mean you can't try using them in places. Your ears are always the
judge!
Extra
info...
One way to see triads is a sequence of major 3rd and/or minor 3rd
intervals. For example:
Major triad = 1
- major 3rd - 3
- minor 3rd - 5
Minor triad = 1
- minor 3rd - b3
- major 3rd - 5
Diminished triad = 1
- minor 3rd - b3
- minor 3rd - b5
Augmented triad = 1
- major 3rd - 3
- major 3rd - #5
Triads exist on the fretboard in many different shapes and
positions. For example, if you've learned
barre chords, you'll most likely be familiar with these six
string major (1 3 5) and minor (1 b3 5) triad forms...
Even
though there are six strings being used in these chord shapes, there
are
still only three tones (the triad) in the chords. We just repeat some
tones to fill
out the voicing of the chord.
Barre chords are useful, especially when it's just you playing, but
this lesson is all about
economising our triad playing for more of a voice leading effect. As
there are three notes in a triad, we
only need three strings to voice the chord.

In each of the shapes below, look at where the root (1)
note is positioned, because this will tell you where to position the
shape to get the chord you want (e.g. for G
major, position the major shape on the root of G)...
Major Triads
Minor Triads
Diminished Triads
Augmented Triads
I'm sure you're wondering... why are the augmented shapes the same? I
won't get into that now, but it's to do with the symmetry of their
intervals.
In
later lessons, we'll look at additional triad shapes that cover other
strings, but the above is a great starting point (and easy on your
fingers!).
Major Scale Triad Harmonization
The
major
scale is the harmonic and melodic basis for a lot of songs
you'll hear (and
write). It contains both the natural (diatonic) major and minor key
centers.
Using the above triad shapes, we can cover the entire width of the neck
on the top three strings in any given key.
The example key I used in the video was A major:
This
A major key corresponds to the A major scale, which we can visualize on
the same three strings "underneath" our chord shapes (if you don't
already know the major scale by
heart, don't worry because we're bringing together a lot of elements
here).

To fully understand how scales, keys and chords are related, take a
look at my Chord Connections course. It's offered many a completely new way of seeing the neck!
When you've established a key, simply find the scale's root (1)
on one of the top three strings and build its related major triad
shape. So for A major, there are three positions as shown below.
This is our I
(or tonic) chord...
For the next triad in the scale (ii)
we move each shape up by one note. The root becomes the 2 of the scale...
On to the iii
chord, again we move each note in the ii
chord up by one degree. The root becomes the 3 of the scale...
Follow the degrees of the scale up to the IV
chord...
V
chord...
vi
chord (our relative minor key tonic, F#m in this case - more on this in
another lesson)...
and the vii
chord - the "odd one out" because it's the only diminished triad in the
scale...
So we now have three positions for each of the seven triads that exist
in A major. Amazing how it all fits together isn't it?
Together,
these triads make up the seven notes of the A major scale. Hopefully,
by following this process, you can see the intrinsic connection between
the "parent scale" and its chords.
So what if we wanted to harmonize a different key? Simply move the 1
of the scale (the root of the tonic major chord) to the appropriate
note. For example, for C major harmony, we'd move the 1 to the note... C
and build the sequence from there.
Your task is to explore this triad sequence in different keys so you
can internalize it and commit it to memory. Take your time.
To
make this process more fun, and to test your knowledge, come up with
exercises that move between the triad degrees in interesting ways, like
the following (we're back in A major again)...
Listen closely to the melody you create as you move between chords.
This is the musical statement formed through the movement of each note
to the next. For example, you could focus your ear on the highest note
in the triad as the melody, the middle or the low note. More on chord
melody another time.
Remember you can also arpeggiate these chords (play them one note at a
time). Go nuts!
As demonstrated in the video, we can also harmonize the scale/key by
using two string, root-3rd forms...
The more ways you can come up with to explore the fretboard in this
way, the
better.
The
whole purpose of this method is to bring together harmony and melody
into a unified musical expression. Use the scale as the "scaffolding"
for your triad playing, even embellish your triads with short melodic
phrases.
The great thing about this method is, once the roadmap
is memorized, you can improvise ideas fluidly and musically, without
getting lost.
