A triad is a chord with three notes. When in root position, each note is a third away from the last. Triads are the most common chord structure and the basis of how other types of chords are constructed. There are four types of triads:
· Major
· Minor
· Augmented
· Diminished

Major Triads:

Hopefully you’ve read about major scales already, this will be a lot easier to understand. If not, it’s still not that hard. The easiest way to think of a major triad is to stack the 1st, 3rd, and 5th notes of a major scale on top of each other.

Minor Triads:

Minor triads are constructed in the same fashion as major triads, only based off the minor scale.

Augmented Triads:

Augmented triads have a cool sound, very mysterious. An augmented triad is a major third on top of another major third.

Diminished Triads:

A diminished triad has a dissonent sound to it. It’s built using two minor thirds.
