1. What are triads on guitar?
In music, triads are groups of three notes, the fundamental, the third, and the fifth. We can also call them “three sound chords”. We can find this family of chords in a lot of music styles.
Here is an example of basics triads:
There are different types of triads: open, closed, and perfect.
It’s composed of three notes: the fundamental, the third, and the fifth.
It’s the note who gets the name of the chord. For example: in a Cm chord, C is the fundamental.
It’s often the lower note in the triad.
Here is an example of triads with a root position:
It’s the note which is two steps next to your fundamental (for the tones, depending on if the chord is major or minor). It’s this note which defines if the chord is minor, major, or sus (the third is replaced by a second or a fourth).
To resume really simply and quickly: a major chord sounds happy, and a minor chord sounds sad.
If the chord is major: the note is situated two steps next to the fundamental (this is equivalent to four frets on the guitar).
If the chord is minor, the note will be at 1,5 steps from the fundamental (so 3 frets on the guitar).
You will find an example with this position just behind.
It’s the note who gives the power to the chord (like in power chords). 3 possibilities for this note:
It can be perfect, flat, or sharp.
In case the note is lowered: she will be at 6 steps from the fundamental.
To write it: we have to add a b5 after the name of the chord (Example: Fb5).
In case the fifth is perfect, she will be at 7 steps from the fundamental.
We don’t change anything in the notation of the note.
In case the fifth is augmented: she will be at 8 steps from the fundamental.
To write it: we have to add a #5 after the notation (Example: A#5)
What’s the difference between an open, a closed, and a perfect triad?
The perfect triad is its most simple form: tonic-third-fifth in one octave.
The closed triad is compact but can be reversed.
In this case, the third and the fifth can be replaced with the bass.
(so we have either T-3-5, 3-5-T, or 5-T-3).
The opens triads are more extensive.
Degrees can be moved to higher octaves, so we increase the ambitus.
(the extent from the lowest note to the highest).
2. Why using open triads?
Open Triads are one more tool we have to tell the same story in a different way. They sound amazing if you are going for a fuller and thicker sound but you still want to play simple triads, and not playing 7th chords, which give you a more complex and jazzier sound.
These are simple forms, easy to use, and we can find them in all the music styles. They allow to be well located on the neck and to find the location of each note. Developing them will permit you to work on complex things after. We don’t see the chords like blocks of fixed positions anymore, but we learn how to identify what constitutes them to well control and move them as we want on the neck. We can potentially make everything by manipulating just the triads.
When we combine and manipulate correctly, we can recreate 4 sounds, enriched chords, and even scales. Some guitarists who have got a very complex playing like Lage Lund, use triads a lot.
Why does learning the triads help us to know the place of all the notes on the neck?
We learn to place the important intervals and their geographic locations on the neck. It gives solids bases and in-depth knowledge of the guitar. The first condition to locate well a triad is to know the place of all the intervals, starting with the fundamental, which implies identifying each note everywhere on the neck.
3. What are the major open triads shapes?
As we mentioned before, a major triad has one root, one 3rd, and one 5th. We can do an Open Triad out of a Close Triad by raising an octave of the middle note, but we can also do that same process for all the inversions, in the different string sets.
For example, the first inversion of C major triad is the notes: E (3rd), G (5th), and C (root). If we make it an Open Triad we get E (3rd), C (root), and G (5th).
The second inversion of C major has the following notes: G (5th), C (root) and E (3rd). The Open Triad of this one now would be G (5th), E (3rd) and C (root).
A Minor Triad has one root, one b3rd, and one 5th. If we go through the same process we did with the major Triad with the Minor Triad now, we get the following shapes.

How can I practice them?
First we have to memorize the different shapes, knowing every time what note is the root in each voicing.
As a second step, I love to play Etudes to practice in a musical and fun way the new shapes. Here is a Etude I wrote:
