In this tutorial, we're going to learn a cool music concept that every guitar player should have in his/her arsenal: TRIADS! Triads are super useful in a lot of situations: constructing new chord shapes, improvisation, soloing all along the fretboard. Let's begin!
Guitar Triads Interactive Tool
The tool below shows you where the triads are located on the fretboard. Click the start button, the tool will display the shapes of the four main types of triads: major, minor, augmented, diminished, in all the possible positions and inversions. Note: all the shapes are shown with the note C as root, you can shift them up or down the neck to play a triad with a different root.

In music theory chords are represented by a harmonic set of three or more notes. These simplest three note chords are known as triads; they form much of the basic building blocks of western music.
During this article we will breakdown the science of guitar triads: how to play triads on guitar, how to find triads shapes on the fretboard, and why it is so important to learn them.
In the late Renaissance music relied heavily on counterpoint techniques, which focused on melodic interactions, and less on harmonies.
With the rise of the triad, music became more oriented towards the specific and simultaneous soundings of particular notes, i.e. chords.
Regardless of the musical scale we play in, when we follow the rules of triads, we will have pleasant sounding chords and harmonies on our guitar!
Ok, triads seem to be cool, but what they really are? A triad is a set of three notes that can be stacked in thirds, lets use the simplest musical scale of C to break this all down.
A major triad is made up of the 1st or root note, the 3rd note, and the 5th note of a scale. The C major scale consists of the notes:
C D E F G A B C
We can have major, minor, augmented and diminished triads, as we're going to see in the following of this article.
Using this scale we will find the notes of the C major triad:
C D E F G A B C
The root and 1st note is of course C the 3rd note as we count up the scale is E and the 5th note is G which makes the C major triad or C major chord C-E-G. It is ok to label this interval either way, or even to simply call it the C chord.
Beyond expanding your knowledge of the guitar fretboard there are a couple of major benefits to triads.Arpeggios, melodies, and riffs are all often composed using triads and their different shapes. An arpeggio is playing a chord one note at a time as opposed to all at once, it can be played slowly or quickly, and in any order you want.
Instead of playing that 5th fret C major triad all at once, try plucking each string quickly one after another. Arpeggios can sound beautiful like a harp solo, or they can sound like heavy metal when played fast enough (with some more distortion too!).
The three notes of each triad, the root, third, and fifth position make up much of the basic harmonies of all pop, folk, and rock music out there.
By just playing these triads in various positions on the guitar, you will have the chops to play in a simple band.
Over time you will want to expand on your triads, but you would be surprised how great you can sound with just the 3 note major and minor chords.
Many guitarists use these shapes to come up with new riffs, melodic lines, and of course for soloing.
Let's say your band has 8 bars of repeated chords C, G, and F... for a simple solo you can play each note in the triad of the chord you are in.
This is a great way to learn to solo and improvise, it is hard to go wrong with the notes in the basic triads of each chord!
Video Demonstration with Tabs
The video below shows a little song that is a demonstration on how is possible to play a common chord progression, such as the classic C G Am F, all over the fretboard, using 3 strings triad shapes. Notice how new shapes appear along the fretboard and the feeling created.

We can also use the terms of half-steps and whole-steps to describe a triad. If you take a moment to pick up your guitar you can get a better idea of this method. Each fret on the guitar is a half step up from the last, if we move up two frets than that of course is a whole step.
Depending on the distance between the notes composing the triad, we can have different triad types, each one with its own unique feeling. Have a look at the chart below:
Structure: Root, Major Third, Perfect Fifth
A major triad is composed by stacking a major third (2 steps) and a minor third (1 and a half steps).
To create the C major triad using steps we start with the root note of C and move up two whole steps to get E and then we move up one half step and one whole step to get to G.
That is the formula for all major triads or major chords on any instrument, we find the root take two steps up to the 3rd and then one and a half steps to the 5th.
Using this simple formula for major triads we can find any basic major chords necessary. Let’s say we want to find the G major triad, well the G major scale is:
The root note is G the 3rd is B and the 5th is D and if we look on the guitar fretboard we will notice that the same formula works again; two whole steps up to the 3rd with a half step plus a whole step to the 5th.
If all of that seems a little confusing, just take a moment away from reading and spend some time studying your fretboard. Try forming different major triads for other scales, and be sure to check your progress. Next we will move on to minor triads... and if you have any frustration over music theory.
Remember there is method to all this madness. By understanding the concepts of these triads your playing, skills, and even your ability to compose and solo will be greatly enhanced.
A minor triad is composed by stacking a minor third (one and a half steps) and a major third (2 steps).
Structure: Root, Minor Third, Perfect Fifth
Say we are playing a C major triad on our guitar, now we all know that major chords are often used for an uplifting and rocking feeling, but let’s say we want to change the mood of that chord.
How do we play the C minor triad/chord? Well of course we could just look it up, but it is a huge time saver to remember that a minor triad simply has a flattened 3rd note!
Before we had the C major triad made up of the 1-3-5 interval, which was C-E-G, now when we flatten the third note we get C-Eb-G, the C minor triad!
It is really that simple as 1-3b-5. Jumping from the major to the minor is simply cutting back a half step on the third note.
Now if we use the step method, a minor triad is one half and a whole step from the first to the third, and two whole steps from the third to the fifth. Each time, with every single scale we pick, the minor triad or chord, will always be this same formula. Above we mentioned the G major triad, so what would the minor be? After flattening the third it is G-Bb-D!
With knowing how to form all basic major and minor triads, our musical world has opened up immensely. Now let's see the remaining triad types, diminished and augmented triads.
A diminished triad is simply a minor triad with a flat 5th. It is made up of the root note, a flattened 3rd, and a lowered or diminished 5th, thus a C dim chord will consist of C-Eb-Gb.
Structure: Root, Minor Third, Diminished Fifth
When you first hear a diminished triad played you will immediately notice how dramatic and even eerie it can sound.
There are a few different ways to notate this triad either as C diminished, C dim, or Cb5.
Certain triad shapes are perfect for learning multiple chords on the guitar. Let’s take the C dim shape above and move it two frets up, the notes will now be D-F-Ab, which is a D diminished chord. As long as we stick to this same shape up and down the fretboard we will have a variety of diminished chords.
The diminished triad is most often used as an approach chord, waiting to be resolved by moving the 3rd and 5th one half step up. Play the notes C-Eb-Gb and then move to C-E-G and you will see how nice this resolution sounds, it has an unstable quality just waiting to be wrapped up nicely. Now, before we get into any specific examples let’s take a look at augmented triads.
An augmented chord is a major triad with a raised 5th. So a normal C major C-E-G becomes the augmented or raised C-E-G#.
Structure: Root, Major Third, Augmented Fifth
This triad can be notated as C augmented, C aug, or C+, like diminished triads they also have an unstable sound and are often looking to be resolved to another chord.
Just like the other triad shapes above we can move this shape up and down the guitar, always getting an augmented triad.
In fact, if we use the diminished triad shape we learned from above we can move that up to the regular C major triad and then raise the fifth up to the augmented C. I personally like how it sounds to play the triad or chord progression:
Because these chords have a bit of dissonance they are often used for a very short time, perhaps in passing for one beat or maybe one bar. They work best as a leading tone into another chord, quite often the root or tonic.
These augmented and diminished chords create an anticipation and transition between normal major and minor triads. They are to be used sparingly in most cases, a little goes a long way! Sometimes songwriters also use these augmented and diminished chords to modulate between different keys in a song.
Many stringed instruments have specific triad shapes to be used and memorized while playing. It is a helpful way of always knowing where to find the basic notes of any chord. This could be a life saver during improvisation and jam sessions.
It will take some initial memorization of these triads when you first start to learn them. Pick a major triad shape and make sure you play the root, third, and fifth, and pay attention to which inversion you are playing.
Once you have the shape down move it up and down the fretboard calling out each chord as you come to it. Continue to also practice this with minor triad shapes in all their forms.
To help you memorize triads shapes, we have create an interactive tool, the Fretboard Cyber Trainer, use this software tool to help you get started on the variety of triad shapes to learn and memorize fretboard intervals.
Note: the tool allows you to practice on all intervals kinds, such as 7th, 4th, 9th and so forth. If you're learning triads, you've just to master 3rds and 5ths
Before we show all the triad shapes, we first must comment on inversions. Inversions deal with the relationship to the bass note of the triad.
- G Fifth
- E Third
- C Root
In a regular C major triad, the note order is C-E-G, with the C note being the bass note of the chord. This chord is in its root position.
- G Fifth
- C Root
- E Third
Sometimes we play a C chord shape on the guitar where the notes are arranged as E-C-G, this is still a C major triad, but it is known as the first inversion.
- C Root
- E Third
- G Fifth
If we have the G as the bass note, this is the second inversion. These inversions allow us to play the same triad in different positions and allow for different musical voicing’s.
Here below you find the fretboard maps for all the triads. Any combination of Root, Third (major or minor) and Fifth (perfect, diminished, or augmented) forms a triad. To see the shapes one at a time, you can use the interactive tool at the top of this page.

Now once we have the basics of the major and minor down, we can begin to build more on our chords. Remember that the major triad is the root or first note, the third, and the fifth... beautiful music occurs when we start to stack more notes onto these original three.
Hopefully now you have the basics down for major and minor triads, how to form them, what they mean, and what they can do.
However, it is always helpful to have some ideas of what others have done with these simple 3 stacked notes. Of course there are a bazillion songs out there that use triads and arpeggios.
So let’s pick one of the more famous pieces out there to give a great example, the song by Led Zeppelin "Stairway To Heaven"
Now awhile back in the news there was a story that perhaps the opening riff to Stairway was borrowed from another band.
Of course all musicians are known for doing this, and there seems to be some striking similarities, but we are not here to point out these potential legal discrepancies, we want to point out how that amazing intro was simply triads being played.
It starts with an A minor triad, followed with arpeggiated major chords like G#, C, D, and there is even a major seventh stacked onto an F triad!
There almost could not be a more famous example of how useful, popular, and great sounding major and minor triads can be! The next time you play or listen to that song, remember, triads are just plain terrific!
One great example of a song that includes both augmented and diminished triads happens to be Stevie Wonders song “For Once In My Life” The chord progression of the verse in this song is:
C C+ C6 C#dim7
He first starts with the C chord, jumps to the augmented C, moves up to the C6 and then to the diminished 7th of the C#.
These chords are great at building a little bit of musical tension and sounding like a perfect mix of pop rock and jazz.
Other examples of songs using C major and C augmented chords are John Lennon’s “Starting Over” and “Baby Hold Onto Me” by Eddie Money
To find some examples of diminished chords one needs to look no further than Christmas tunes. Jingle Bell Rock, Let It Snow, Little Saint Nick, Winter Wonderland, and more all have diminished 7th chords in them.
In fact, so many tunes from the 20’s and 30’s have these diminished 7ths that it is known as the “diminished cliché”.
The best way to use these dim 7 chords are to jump a half step up from the chord you start at.
Instead of playing Cmaj and then Dmin, try Cmaj to C#dim7 and then to Dmin. The latter sounds far better and will increase your musical palette.
You will find the best songwriters use augmented and diminished triads to “pepper” their music with more sonic layers. The Beatles often use these triads in their music. It doesn’t take much to really change or add to the sound of a simple chord progression.
Their song “Oh Darling” starts out on an Eaug7 chord, that is made up of E-G#-C-D.
A regular E chord is E-G#-B, just think how different that song would be if they played a regular Emaj instead of the Eaug7. That augmented 7th is only played for one bar but really creates a bit of initial musical tension leading into that song.
There are plenty more examples out there of augmented and diminished triads. By practicing the specific triad shapes you will become more familiar with how they sound, eventually you will be able to listen to your favorite music and pick them out.
Remember the purpose of augmented and diminished triads is to create a dissonance and instability that must be resolved into a better sounding chord!
This concludes our journey into the fascinating world of triads and harmony. Actually, learning triads is just the beginning: there are a lot of interesting things you can do, such as adding another tone and creating seventh chords, and other funny things.
